The blazer, keeping it, beginning to restore, need some help.

I was attempting to sell my dads 1972 K5 4x4 Blazer but have now decided to keep it and work on it myself. Here are some pics, and a few questions.





Now the first thing I want to do to this truck is seal up the doors! Every time it gets wet water gets on the inside and sits on the carpet, and it is starting to rust out the floor in the corner on the left side! I think I am going to need some new rubber for this. I am not sure what all I need to order however, or how difficult this would be to install. Any suggestions?

Once I get it all sealed up nicely, I'm going to replace some parts like the back bumper which has a nice dent in it, fix the rust on the rocker panels and what is forming on the floor, and repaint it. My dad wanted it orange so that's what I'm gonna go with.
