Spellcasting
I believe this reasoning is incorrect for reasons I will attempt to outline below.
Epic destinies and multi-classing
A Warlock does not cast spells (it has invocations, like a monk has ki attacks); neither do fighters, rogues, or barbarians, but given their use of magic-like attacks, a monk may be the best point of comparison. In all cases, classes without spells points (fighters, rogues, barbarians, monks) are still able to make use of Epic Destinies, even those with abilities that cost spell points. In particular, the feat Magical Training is available, as are spell point items, and, for those Epic Destinies that are particularly spell point dependent, such as Draconic Incarnation, spell points are included in the Epic Destiny. If Epic Destinies are to be the justification for giving Warlocks spell points, it is very inconsistent to not give spell points to fighters, rogues, barbarians, and in particular, monks.
Similarly, it does not make sense for a non spell-casting class to directly add power to a spell-casting multi-class. Despite the fact that monks also have magic-like abilities, they do not receive additional ki from multi-classing, say, sorcerer or wizard; neither does a wizard or sorcerer receive more spell points for being a multi-classed monk with magic-like ki attacks. If ease of multi-classing spell casters is to be the justification for giving Warlocks spell points, it is similarly very inconsistent to not give spell points to fighters, rogues, barbarians, and in particular, monks.
Wizard and sorcerer spells
Warlocks invocations are not equivalent to wizard and sorcerer spells obtained at the same level. In particular, they are not balanced as being equivalent. For example, a level 8 arcane spell is balanced for casting twice per day by a level 16 wizard and three times per day by a level 16 sorcerer, whilst a dark invocation is balanced for casting an unlimited number of times per day by a level 16 warlock. As a result, high level wizard and sorcerer spells are very powerful in comparison to warlock dark invocations.
The proposed spell book allows Warlock's access to wizard and sorcerer spells at an earlier level than even wizards and sorcerers! For example, in the initial proposal, a Warlock can cast Finger of Death (or say Greater Teleport) at level 13, a sorcerer cannot cast Finger of Death (or Greater Teleport) until level 14. Similarly, the proposed warlock can cast Wail of the Banshee (or say Hold Monster, Mass) at level 16, a wizard cannot cast Wail of the Banshee (or Hold Monster, Mass) until level 17, and a sorcerer not until level 18. Furthermore, even at level 20, a sorcerer can cast from a selection of three level 9 spells (say Wail of the Banshee, Hold Monster, Mass, and Power Word: Kill) at level 20; the proosed Warlock is able to cast from a selection of all three of these at level 19.
With the proposed spell book system, even feats are likely to be very similar between a Warlock, and a sorcerer or wizard, with Spell Focuses in say enchantment or necromancy. Moreover, given the very small proportion of spell points that actually come from cast levels, when compared to the bonus spell points that come from casting ability score, and additional bonuses from items and epic destinies, it seems that the proposed Warlock is very powerful compared to wizards and sorcerers, and also receives better hit dice, better proficiences, and eldritch blast!
Invocations
The total number of proposed wizard and sorcerer spells in the proposed Warlock's spellbook is 12 (6 of each level from 1-6) at level 20; there are also 6 added spells based on pact, and eldritch blast shapes and eldritch essences are added through enhancement trees. The (standard, edition 3.5) Warlock gets 12 invocations at level 20 including all eldritch blast shapes and eldritch essences. This gives the traditional Warlock a feel where the Warlock may not have the right tool for the job, and must try what it can with a very limited number of infinitly-usable invocations. I think the proposed Warlock, particularly with the spellbook, does not have this feel. Instead, I think the proposed Warlock will feel very much like a sorcerer or wizard, with approximately the same number of spells/invocations as a sorcerer, and even possibly with the very same level 9 spells! Finally, there are many wizards and sorcerers who do not cast direct damage spells.
I know you are aware of the Warlock invocations that exist, and that you hope to add them; I would of course very much like for this to be the case. But, at least initially, if for development resource reasons we are limited to existing wizard and sorcerer spells, I still believe it would be far better for those selected to be infinitely usable! I would also suggest to not offer spell focus feats or bonuses from items, but to instead offer invocation focus feats, and to most certainly not use spell components; a Warlock is not a wizard or sorcerer.
Please do not use spell points for warlocks. Warlocks must have genuinely unlimited use of their invocations. This is the defining feature of the class, and to have spell points, to me, defeats the entire purpose of the class.
Eldritch blast
I find the idea of replacing the 'attack' with eldritch blast interesting. As long as blast shapes and eldritch essences are reasonably changeable, whether it be via toggles or some other method, I think this will be good. I also thank you very much for making eldritch blast infinitely castable! I am quite excited to see it in action! I think it is sounding quite fun, and only have two other comments below.
First, I would make the basic eldritch blast untyped damage. This will scale with force spellpower, and kinetic lore, as (as far as my understanding goes) with other untyped spells. Otherwise, as has been pointed out, how would a Warlock kill a Helmed Horror?
Second, I would not allow metamagics to apply. Otherwise, maximise and empower become almost required, and the feat selection, particularly if spell points and wizard and sorcerer spell books are used, would almost exactly match a wizard or sorcerer (various metamagic feats and various spell focus feats). I do think that an Epic feat Improved Eldritch Blast or some such would be a fine idea, and consistent with the Epic feat Improved Sneak Attack for rogues.
Pacts and alignment
All the pacts and enhancements all look quite exciting. I only have one brief comment: any kind of abundant step ability is extremely powerful. Putting it in one pact will mean quite a lot of people choose that pact for that reason. Even putting it at tier 5 in an enhancement tree will mean quite a lot of people choose that tier 5 enhancement tree for that reason. The number of Air Savants is in no small part due to this. And as a declaration of bias: my character's tier 5 enhancement tree is currently Air Savant.
I only mention alignment because of the number of other comments. I had assumed any chaotic or any evil, or for DDO say any chaotic or any neutral, but for me this is not a big issue at all. Certainly, spellcasting with spell points is my biggest concern!
Hit dice, BAB, saves, etc.
All look good to me! I think the only basic statistics you didn't mention were weapon/armour proficiencies.
