Newbie starting first project, where do I start?

[PirateToast]

Sorry if this is the wrong place for this post.

I drove a '91 2.3 in high school. I have fond memories of it and always wanted to have 5.0 project car. Researching, I found the early 80's T-Tops stangs and fell in love. I've wanted to take a project and turn it into something like this that I found here: http://vb.foureyedpride.com/showthre...USTANG!/page17

So this weekend, I bought the attached car. It's in rough shape, but checks the boxes for what I'm looking for. It's an '85 GT with T-Tops. It runs, but it runs pretty rough. Needs a lot of cosmetic work as well. I guess my question is where do I start?

1. The engine runs very rough, there's some sort of aftermarket fan installed on it as well, I'm not sure what those switches are all about.
2. There's a lot of cosmetic work that needs to be done.

I've attached a few photos. Any guidance would be hugely appreciated.
