You can reuse your Lifters (you would have to removed the heads to replace them anyway). New Head gasket, should be able to reuse Timing cover and water pump gaskets. New Balancer Bolt.
You can get some new LS6 spring pretty cheap. If not, go with the Comp's 918's
Not sure about the 5.3L cam, but the LS6 cam is a small base cam, you would need 7.425 push rods (at least fro a LS1 to LS6 cam you would).
Would suggest new LS2 timing Chain and Oil pump as long as your there.. a Ported LS6 would be good.
I am sure everyone else will chime in...

so in that case it should be noticeable. is there anything else i can do to get more power from just what im doing with the cam?
is there a different cam that wont break a budget?
im sure i could get a ls6 cam for cheap used with low miles.
or find a different cam, because i wouldnt mind a nice lope

It may be 25-30 hp, but it will be up in the RPM range b/c it has a 117* LSA. What exactly are you trying to achieve here? You would need some pretty good stall to get this thing moving in a heavy truck.

The 212"/218" profile is great on 5.3's and on 113* + 4* it will make tons of torque down low with a little (slight) chop at idle. It should also pull up to 5500-5800 in a 5.3. I have the Comp Cams version 212"/218" low lift and its great, but think the Cam Motion would work better in your application. Use the cheap LS6 yellow springs and 7.425" push rods to complete the package.
The '02 - '04 LS6 cam will make your truck feel like a VTEC motor with almost no power down low and screaming up top...not what you are looking for.
