Need a suggestion on some Bodywork Tools

I've decided to start the bodywork on my Dart and need a suggestion on some tools to get started. Mostly what i will be doing is pulling dents, probably won't have to replace any panels from what i can tell. There is only minor surface rust so that shouldn't be a problem. I found a couple of hammer and dolly kits that i'm thinking of getting:

or

The first one is quite a bit more, but that's okay if it's better quality and has more of the things i will need. I'm also considering a stud welding gun:

Is this set worth the money or should i get a cheapy Harbor Freight one?

Also looking at getting a D/A sander and some durablocks. Anything major i'm missing that i'll need to get started?
