No idea where to begin!

I'm currently in the process of restoring a 68 dart. The first thing I would like to do is do a complete paint job, so I'm taking everything off the car, pulled the interior out the other day and tomorrow goes the tranny and engine and exhaust.

Aside from taking everything off the car, what do I do next? It has some small rust spots and some surface rust and a little bit of dings here and there. I don't know if I san the whole car down first or just the rust areas.

So yea, as far as taking it apart I have no idea what to do next

Help!
