Gear for levels 20+

Hello,
Currently leveling my evoker fvs to level 25. He was TRing a lot and i kind of forgot to prepare some gear for him, so now i have a bunch of past lives but very lame gear.

I would like to ask you to post your end game (meaning for levels above 20) gear setups. I know we dont know all the future gear in expansion yet, but i need something to be able to even join that raid and other old epic elites.

helm:
necklace
trinket - planar focus with +3 insight. wisdom (250sp, Spell pen IX set - dont know what is the other item in the set)
goggles - conc op goggles (150sp, conc op)
armor - spidersilk robe (+3 insight. charisma, potency, wizardry IX, resistance +6, toughness, conc 15)
cloak - epic envenomed cloak (+7 CON, GFL)
gloves - shroud 45HP Mineral (heavy fort)
belt
bracers - bracers of the sun soul (+7 WIS, insight. CON +2, sup parrying)
boots epic boots of corrosion (+1 exc WIS,free green slot)
ring1 - tod ring (+1 exc CON with +2 ins CHA)
ring2 - signet of shining sun (+7 CHA, +2 exc WIS, sup healing lore)

These items cover - CON +10, WIS +13, CHA +13, 45 shroud HP, GFL, toughness, heavy fort, 150 shroud SP, resistance +6, concentration +15, superior healing lore, potency, wizardry IX)

Couple slot left empty so far, what to put there?
What i would like to slot - Spell penetration IX (or greater), some sort of Lores, devotion, impulse or radiance items, greater evocation and necromancy focus.
I know most of spell power and focus items come on weapons or can be crafted and are easily swapable. Perfect item would be Holy symbol of Lolth (Radiance +102, Impulse +102), but +3 insightful wisdom seems more important.

Any advice appreciated or post just your planned setup.
Thanks!

Is it really worth a slot to you for +1 exceptional con on your ToD ring? Same thing with the Signet of the Shining Sun, that's at least got +7 cha/sup healing lore which is alright, but the +2 Insight Wisdom is wasted.

Spell Penetration 9 is still a really limited stat with what we know. The Erudition set bonus and Staff of the Necromancer are the only new items with it. I guess you could ditch your ToD ring and grab an Epic Shaman's Band if you really want to make sure you've got Spell Pen 9 all the time. Or just throw on the Staff of the Necromancer when you need it.

I was trying to push charisma higher, because 2 of Exalted Angel abilities have charisma based DC. If I end up not using them at all, i wont probably bother with charisma that much.

Thanks for the Shamans band tip, forgot about it. Might even used it with necklace for evocation.
