Thoughts on a build?

[Pit-ik-cha]

My DM is having a level 20 gestalt campaign. He says only to worry about the level adjustment. Ability rolls are 5d6, reroll ones and twos, take the top 4.

My build is:
Thri-Kreen: Deflect Arrows, Psionic Fist
Flaws: Shaky, Inattentive
Free flaw feats: Run, Combat Expertise
1: Lion Spirit Totem City Brawler Barbarian/Chaos Monk: Improved Unarmed Strike (LSTCBB bonus feat) Multiweapon Fighting (LSTCBB bonus feat), Improved Grapple (CM bonus feat), Iron Will
2: LSTCBB/CM: Combat Reflexes
3: LSTCBB/CM: Great Fortitude
4: LSTCBB/CM
5: LSTCBB/CM
6: LSTCBB/CM: Improved Multiweapon Fighting (LSTCBB bonus feat), Improved Disarm (CM bonus feat), Greater Psionic Fist
7: LSTCBB/CM
8: LSTCBB/CM
9: LSTCBB/CM: Toughness
10: LSTCBB/CM
11: LSTCBB/CM: Greater Multiweapon Fighting (LSTCBB bonus feat)
12: Firestorm Berserker/CM: Instantaneous Rage (FB bonus feat), Unavoidable Strike
13: FB/CM
14: FB/CM
15: FB/CM: Psionic Meditation
16: FB/LSTCBB
17: FB/LSTCBB
18: FB/Psychic Warrior: Speed of Thought (PW bonus feat), Reckless Rage

We get 100,000gp, only limit being no epic items.
Monk's belt
Boots of Striding and Springing
+2 CON, +2 STR, +2 WIS Ioun Stones
+3 Amulet of Mighty Fists
Grey Bag of Tricks (for S&G's)
Ring of Jumping
Standard Adventurer's Kit
Monk outfit
80gp leftover

DM ruled that LSTCBB and FB stack in gestalt.
I grabbed the Lion Spirit Totem variant stuff at levels 1 & 7. My Psychic Warrior power is Prevenom.
Also, full ranks in jump, synergy from tumble, ring bonus, boots bonus, racial bonus, and a +8 STR mod = +71 Jump bonus. +75 after 20' running start.
Also his total movement speed is 110 ft. (12.5 mph walking, 62.5 mph running).
