Excellent job, my friend - I think that Gary would be laughing his arse off at that Tomb of Horrors bit - I know I did.
And just for this tribute, and for Gary, I think I might try to make a dual-lance wielding Drow cavalier for my next game. Cavalier prestige class, Oversized Two-Weapon Fighting, and a Dominated Unicorn oughta do it. I think that Mr. Gygax would slap me.
