Probably models ending in x163 for a 3" lift application (rear), or x095 for a non lifted application (rear).
Just measure your existing fully extended and compressed lengths, choose the type of ends you need. and find a shock model that has your desired characteristics. I put on a set of their rebuildable external reservoir shocks, and I absolutely love them. Best shocks I've ever had.

As for tires, I hear that the Pirelli Scorpions are real nice, but I'm sure theres someone here that knows street tires better than I do. Perhaps Newthings or Tone could help you pick a good set.
Hope this helps some.
