There used to be a Linex dealer around there somewhere, their kid raced CRA.
As far as bed extender, I use ReadyRamp. Comes in 2 sizes to fit compact/midsize, and Full-size trucks. Folds out and becomes a long loading ramp, then the ends fold in to be the bed extender. Check eBay for them, got mine for about $220 delivered. I think it's worth it.
If you're looking for a "bed buddy" (bar that has chocks and tie-down rings that mounts across the front of the bed), I noticed that PitPosse.com had them for less than most places I've looked before. I have a Tacoma, and there is a guy in the Pacific NW that makes the Yotarack, which attaches to the standard Toyota rail system, no drilling required.
