As Tixer said, the double din shouldn't be an issue. Plenty of us have done it, just take your time cutting.
The best DD dash kit is the Metra 95-5026. Requires a little trimming ( Round off top corners and trim off 2 tabs) but it is by far one of the best options for us. Make sure you have the crossbar portion on the bottom and not the top or else the dash bezel won't sit flush.

The wrong way...
I like the equipment you chose though, what guage are you going with for power/ground and speaker?
