BigdogRevo, I would get the P2 rockers, they arent much money, but will help handling alot! The Red Pushrods are lighter and bling, but aren't needed, other then being a little lighter(and sometimes weaker for beginners).
Also a better radio will help, but the more important thing is the steering servo. I use any of the better ones from Futaba(9451) or Airtronics(--360).
There are less expensive brands out there too, just make sure you have at least 100+ inch ounces of torque and a transit speed of .16, 60 degrees at 6V or faster.
The last needed mod, imo, is the tires, I like Panther tires, or Proline Bowties on dish wheels if available.
The starter and reverse elimination, as well as the close ratio gear set are hop ups for later on, after you get more familiar with the truck.
