1973 Pontiac Ventura

Howdy y'all. I just decided that I'm going to undertake the project sitting in my backyard. I have a 1973 Pontiac Ventura with a 350 in it. I don't know what is wrong with it, all I really know is that it has a 350, its an automatic, it needs a new interior, its blue, and it needs some work. My question is, where do I start? I've never rebuilt and engine before, but I do have help if I need it. I'm looking into buying one of those how to rebuild SB chevy books. Any suggestions?

Thanks

(And any other tips are also appreciated)

This is the finished look i'll be going for.
