Boosting up a fighter

[WarKitty]

I need good passive feats to boost up a fighter-type. The particular character class is a homebrew based on a fighter/barbarian gestalt. The party is about due for their (also homebrew) prestige classes, and I'm frankly a bit at a loss as to what to do for this person. I would like to make him into a sort of damage sponge, with maybe a bonus to his to-hit. The player isn't into the game enough to want to mess with a lot of special abilities.

Shape soulmeld: Mantle of Flame, Blink Shirt, and Astral Vambraces. Vambraces needs arm chakra opened to get flight, a slam attack, swim or energy resistance.
Bind Vestige Chain can give you an ability that is kind of like flight, and several other abilties. Like Full Plate at low levels.

a ToB stance could be great (requires a ToB maneuver though)
