Welcome Steve!
Here's a link for how to add pictures-it can be found stickied in the For Sale section.

Sounds like you have the car planned out pretty well. Tons of info on here and willing members to help you out.
The turbo air damn will have plenty of clearance with 1.5" springs.
What is the offset/width on the 13's you have? That will determine if you can run them with flares (and not look goofy). You'll need a wide wheel/low offset to fill them out, and a 6" wide wheel with 205's won't quite do the job.
Good luck-looking forward to seeing pictures.
Cheers,
