anyone, any advice?

Well, you can get the rods and crank out of a junker, no sweat. Personally I'd have a machine shop balace the whole rotating assembly. If you are doing a rebuild at the same time, go ahead and check www.summitracing.com for pistons, rings, etc and I'd still let a good machine shop put the thing together. All you are doing is replacing the bottom end / rods crank seals bearings and making sure it balances correctly. The rest of the engine is fine the way it is.
The cylinder head can be the ported HO, the 96+, the Hesco - any damned cylinder head meant for a 4.0 will work. I'd just make sure its HO or 96+ if you want to get the max power out of it.

Lots of stuff you can get on Ebay.

I would have them deck the block at least .020" as well, but that'll increase your cr a couple points.

what octane you plan on running with 9.2:1 compression?

would regular 87 octane hurt it?

im not too sure thats why i asked. 8.8:1 is stock right? i think with 9.2:1 you would probably need 89 octane but there are other factors involved.
