I think "Urban Bomber" would be a nice name! 
What's really cool is that I pretty much have the same thing(except you are a standard cab and I'm a super cab), and I've either fixed or welded or somehow took apart/put back together every square inch of my truck.
I can tell you 2 key spots to check up on:
1. All the leaf spring hangers. The rear ones on mine were almost rusted through, and I have the capabilites to make a new/HD set.
2. The transmission crossmember. It loves to rust out at the actual riveted piece on the frame and on the outermost parts of the crossmember. Again, I could replicate it very easily.
