since you are using the Savage Species racial Progression on one side of the Gestalt .... you should try this:
1)try to avoid losing BAB on the other side of the Gestalt, if possible
2)focus on Skills, Feats on the other side of the gestalt
3)look for classes that give uses for High Attributes(Monk Wis to AC, Paladin Cha to Saves,etc...)
try this:
Trumpet Archon 20//
Monk 2/ Fighter 2/ Paladin 2/ Psychic Warrior 2/ Fist of the Forest 2/ Warmind 10combined with Bonuses from Trumpet Archon(Str +10, Dex +6, Con +12, Int +6, Wis +6, Cha +6)
feats:
Improved Unarmed Strike(monk bonus)
Monastic Training(Warmind)(monk bonus)
Combat Reflexes(Monk Bonus)
Power Attack(fighter bonus)
Combat Expertise(fighter bonus)
Improved Bull rush(psychic Warrior bonus)
Improved Trip(psychic Warrior bonus)
Great Fortitude
Practiced Manifester(Warmind)
Practiced Caster(Cleric)
Shock Trooper
Pushback
Tashalatora(Warmind)

this gives:
