I've found that I'm much better mechanically when I'm working on internal engine stuff, than body related things like suspension or sway-bars. I'd rather do a (valve)spring swap than replace the brake lines on my truck again, if that puts anything into perspective for you...
I think it's completely up to you about going with any more hardware than just springs... there is a ton of info out here on cams and rockers, you kind of have to decide for yourself unfortunately. It all comes down to money, and what you do with your truck.
If money is an issue, you'd be fine just running Comp 918's. Very popular spring, and they'll work as good as any on a stock cam.
Pushrods - some people use stockers as "fuseable links" - theory is, in case you overrev, they bend 'hopefully' saving you from piston to valve contact. Most other people say to replace them with hardened PR's if you do any higher RPM stuff though. I think the stock length is something like 7.365". I'm one of the many people running hardened PR's.
Stock rockers are good. Not like the old style ones that soak up a lot of power. Most people don't think going with 1.8 rockers is a cost effective investment...

wow, thanks marc for all the info. as far as money goes i believe in doing the job right so if you have to save up a little longer then you do. i will eventually replace the cam and other related parts so i was thinking if i have to work on some of the internal stuff anyways then i might as well do my other business while im at it. thanks for your help
