Manu,

Go with #3, or Di It Yourself as its really not rocket science, you just need to have access to the tools and understand all the steps, actually I am doing the exact same thing this weekend.

Zimmerman Cross-Drilled (actually they are not drilled, they are cast into the rotor and are O.E. to many German Auto companies) rotors and EBC Green pads and Stainless Steel brake lines.

I am sure some one here can break down every single tool you will need and give you every step to get it done.

BTW, where did you find Zimmermans for $50 bucks? That is cheap, did they have rear rotors as well?
