first things first- check to see if your throttle cable has stretched. mine was stretched really bad. remove intake tubing from the throttle body, have a buddy hold the accelerator pedal to the floor (with the truck OFF) and see if the "butterfly" is opened all the way. if its not at a 90 degree angle, then it has stretched. do a search for "throttle cable mod" and it will explain in detail how to fix this...
change the tranny fluid and filter. i run B&M Trick Shift synthetic, and love it. others will recommend Mobil 1 or Amsoil. also good stuff. in any case, synth in the tranny is a good choice. get the B&M shift programmer. takes about 15 minutes to install, and you can find them for around $30-40. autozone has started to carry these in stock. worth about 10 times the price, IMHO. you can have your tranny shift however you want at the flick of a switch.
an intake/catback exhaust is also a good start. if you wanna save some $$$ on an intake, here is what i did. get a K&N filter, and cut the stock airbox in half. leave the rear portion on as a "heat shield" of sorts...
