I REALLY like the concept. Très intéressant. Now, if only my DM would like it too...
O.K., here are my suggestions:
As someone else said, the levels he gains the bonus tricks, I wouldn't give him a bonus feat also, I would make him choose (like someone else already suggested). This way, it would still be balanced.
Allow me to give my two cents on each trick:
Close-Quarters Ranged Combat: Really cool, if somewhat strong. It is already a feat in the Epic Level Handbook, so I would give it a prereq. of at least +11 BAB.
Flurry of Strikes: Quite good. Once again, would give it a prereq. BAB +11 though (a fighter doesn't really mind a -2 penalty, like the monk does).
Graceful Combat: I like it as is.
Great Sunder: I don't think someone would take it at +1d6... I would give a straight +4 bonus.
Heavy Weapon: This I really don't like. I would leave that out IMC.
Ranged Disarm: Perfect as is.
Show Off: Oh this is VERY sweet. So many times a fighter player says "I wirl my weapon around to impress the guard" and there's no game mechanic to illustrate this. VERY sweet.
Sneak Attack: I like too. If a rogue is so good at finding the sweet spot in his adversaries, why would the ultimate D&D combatant (the fighter) be denied this ability ? Quite cool.
Stunning Blow: Nice, but I wouldn't put Wis as the modifier. For the monk, it's Wis because his combat techniques are a matter of mind and discipline, but stunning for a fighter should be a matter of brute power. Hence, I would give Str for this fighter ability.
Surprising Strike: I don't see a problem with it, but it's not as sweet as most of the others. Probably won't ever be picked.
Throw Weapon: See above. Furthermore, while a cool move, a fighter throwing his main weapon at an enemy in the middle of a fight is probably gonna go "Duh" on his next action.
Trip Attack: Since it's pretty much covered by Improved Trip, I wouldn't put that here.
Twin Weapon: This is not cool, it's awesome. Beware the munchkinisation of the drow-elf phenomenon. I would give it a very steep prereq., probably BAB +15.
Uncanny Blows: Quite good.
Weapon Defense: Since it's a shield bonus, is it stackable with greater two-weapon defense ? It's also a shield bonus (and almost only dodge bonuses are stackable).
Weapon Mastery: I would ask Greater Weapon Specialisation as a prereq. and just say:"add +2 to the damage of a greater specialized weapon", because of Epic Weapon Specialisation (ELH).
Weapon Parry: Hmmmm... this I'm really not sure about... does this means that a fighter with 4 attacks can use ONE of those 4 attacks to parry ? Many critters out there only have one attack (or two, but often that second attack misses). I have no idea what the power level of this ability might be, but I fear a retributive strike from the game mechanics hitting the DM square in the cojones if he allows this in his campaign.
Overall, no matter what modifications are made to these, I still like the concept MUCH better than the standard 3.5 fighter. Une très bonne initiative selon moi, mon ami !
