Personally, I think you'd be better off simply reinstalling Quake III Arena and possibly Team Arena.
Lost that CD a while ago...

still keep Quake3 installed for the Generations Arena mod if nothing else.
Awesome times. My favorite was the Doom trooper. I remember how they originally wanted to make an super-total conversion with the Quake 2 engine, where they had each id character (BJ from Wolfenstein 3d, Doom trooper, Quake 1 soldier and Quake 2) with their respective weapons, and the levels from Wolf3d Doom, and Quake 1. But that was a little too much for id, so they slapped them with the C&D...
I hope this acquasiton will work out. Bethesda will get a powerful engine, and id should get some fresh ideas. But please, no gun/tank/useless armor...
