New stereo, install help/advice needed

[SoK]

Hey Guys,

I have a birthday coming up and my GF said she'd buy me a new radio. We stopped in Best Buy the other day and I saw this one I liked:

I've read up on it and it seems to get pretty good reviews, especially for the price.

Here's where i need help.

What else do I need to install this? Will this work for the dash conversion?

I'm guessing that should be about it. Let me know your thoughts before I order everything. Thanks
