If all you want is something simple than it sounds like you've found what you need. Just do me a favor and buy the wiring harness that will plug into your vehicle. It will make installation much faster, and won't royally piss off anyone who ever tries to replace the radio again. I can't belive how many vehicles I have seen where the owners cut the factory harness to put in an aftermarket radio. Makes you want to stab someone in the face.

Crutchfield is usually pretty good. They always offer free stuff like the wiring harness, or the dash kit. I have bought from them many many times.
