The A1RM is more of a track orientated pad but will still work on the street. In your case I would go with the HPX. They'll be more than enough for what you need and last longer than the A1RM's.
For tyres, I've used the federal 595 SS's and they've been fine in the wet. At $100ea I couldn't really fault them.
Bushes, I prefer Super Pro over Nolathane, just found them to be a bit quiter and last a bit longer.
The only reason I wouldn't put adjustable Hardrace items in a street car is legality.
Shocks are going to be one of your biggest choices and how much you want to spend. Personally after running Pedders, Monore and a couple of other brands. I'd spend the extra and get some Koni's or Bilstiens for better quality and comfort.
