junkyard fans from either a taurus, contour, or mark viii work well, which one you choose depends on personal preference, space available, and your own personal fab skills (none are a bolt on, you'll have to figure out you're own mounting and wiring).
if you look at toolow91's thread, i think he just got an aftermarket black magic setup that looks pretty cool. i know the old ones didnt really pull enough air, dont know how the new one's work.
for a rad, i run the frpp piece, but griffin, fluidyne, becool, and mishimoto all make good stuff. i was about to say it isnt a needed upgrade with what you're running, but then i remembered the vortec, which boots it up the priority list. be aware though, that all the aluminum rads are going to thicker than the stocker, so especially with the blower you'll have to really think about your fan choice.
