Yeah, PDK for the PRR is very attractive, and Deep Gnome is the other half of that coin w/ MRR. Bladeforged gives +Fort, SDK gives Dodge (unless you're capped?),
And it looks like you have Epic covered pretty well.
An Iconic PL comes w/ a Heroic PL built in, and no good reason to throw that away*. Not sure I completely agree w/ your choices, tho'...
More Monk PL's would only add +1 damage/, so that's very meh. Barbarian is slightly better @ +10 HP/ - as mentioned above, more helpful at lower levels, or once you have 3 lives of it, etc.. However, Pali lives add 10% Hamp/, and that's not insignificant - that would be one of my first choices, all things considered. Also, Fighter lives add to your Tactical DC's (assuming you have some, since you list it - unless that's overkill?).
(Beyond that, Artificer for UMD, and then, ~if~ you use them a lot, Druid for stronger Hirelings.)
(* If, by "I only play a monk", you mean that you will not play anything else, even to gain a PL, then you'd have to come up w/ some sort of monk-ish PL template, either something like Monk 9/X 11 (or 8/12 or 10/10 for some), or Monk 6/6/X 8 (or 7/6/7 for some). GL w/ that - it may sound like a stretch, but a) I'm sure there are folk on these boards who could help w/ that, and be glad for the challenge, and b) it could well be worth it for the PL rewards, esp if it played like a monk (which sounds very doable).)
As for Racial, it would surprise me if you could not find a use for a couple/few more racial AP. You've got 2 AP, and Wisdom covered - an obvious move, gj. I don't know if Spot would be handy (and I'm guessing that Move Silently would not be), but +2 Dex from Elf/Halfling probably couldn't hurt. Similarly, +2 Con (& +1 Balance) from Dwarf/Warforged for that.
As for the rest... +1 Str (and Intimidate?) from Horc for Encumbrance? By the time we get to +2 Cha for UMD? Doubtful, maybe - but remember, they're all +1 AP each, regardless of the gravy, and that's the real goal.
