Snap Kick and Superior Unarmed Strike, both from the Book of Nine Swords, are awesome. If you have Power Attack, check out Flying Kick, from Complete Warrior. Fiery Fist, from the PHBII, is awesomely cool but not super-powerful.
Deset Gled, would you mind expanding on why you don't like Godstorm? I've been seriously considering buying it, 'cause it looks darn cool, and I'd love to get the opinion of someone who's actually played :)
I like the Broadblade short sword from CAdv for AC fighter builds, but it does cut down on damage a bit. Also check out extreme shields from Races of Stone.
If you can, try and get Flick of the Wrist. Requires Quick Draw, Sleight of Hand 5 ranks, and Dex 17; once per combat per opponent, you can quick-draw and make a melee attack with a light weapon, catching your opponent automatically flat-footed.
Hmmmm....

I totally dig Elements of Magic, but that's really a whole 'nother magic system, and without the magic system the classes are nothing special.
I'm currently running two games set in my D&D-in-spaaaaace! world, but they're probably never going to interact. One's set out-and-about in the wide world with lots of planet-hopping, the other's on a single planet cut off completely from the rest of the universe by aether storms twenty years...
I was left wondering why Elizabeth didn't just sign up on board the Dutchman. I mean, she wouldn't be all fishy, and she's obviously comfortable around sailors now...
Elements of Magic: Mythic Earth is the skill-based EoM variant. It's ver' cool, IMO, although it's based on Modern instead of D&D (there are conversion notes).
It's flavor text. Charge the player for some other magic item that goes on your arm and throw in the arm-replacement; that's how the Arm of Nyr (or whoever) worked in Defenders of the Faith.
That's not min-maxing. Min-maxing minimizes your weaknesses while maximizing your strengths. That's max-maxing, maximizing both your strength (blasty-blasty) and your weakness (reliance on PP).
