What would be the best wheels/rims for my CLK 500 AMG "?

Enkei, RPM, Monet...Check Performance Plus Tires website for a large selection of wheels to get you started. When it comes to tires - Goodyear Eagle F1 GS-D3 are far and away your best choice, far superior to the Michelin Pilots and I wouldn't even bother comparing them to any Jap tire. (in regards to the outfit on e-bay, I've never heard of them, and you should figure on at least $2000 for wheels and tires, split pretty evenly)
