2001 jimmy diamond edition 4x4 Looking for advice, my Jimmy's motor is going out and I'm currently debating going back with another 4.3 vortec or going ahead and swapping to cam and headers 4.8.... Anyone done it? Advice?

Welcome to LS1Tech. I say that because you must be new and missed our fantastic search feature. 
It's like Google and I believe even powered by Google and pretty badass. I'm willing to bet there are several S-10 / S15 / Jimmy builds in various stages of completion on this vast site covering most of what you need to know from parts acquisition to completion and track times.
People here (myself included) are VERY helpful answering questions when you hit a snag, but you have to at least try first.

1. Yes, it has been done countless times, maybe not on a Diamond Edition, but on countless other S10 platforms for sure.
2. How much money do you have to spend? Can you fabricate, weld, or turn a wrench? Will you be doing it yourself or is a shop doing the swap? Are you buying a swap kit, or are you piecing some parts together?
3. Advice, search... if you use google, or even the search button on here, and type in s10 LS1, 4.3 to LS, LS1 jimmy, they all bring you results, just read up and figure out what you truck takes to get a LS in there. Your fuel supply should be fine, you'll just need a corvette regulator. Unless you find one dirt cheap, I'd probably look for an aluminum 5.3 or an iron 6.0 and an LS 4L60e to put behind it. You'll need a set of mounts to put the LS in, might need a different oil pan depending on donor engine. Your computer will run the LS, you'll likely need it flashed and you'll need an LS wire harness. Headers are mandatory, so consider that part of the budget. You may also need a bigger radiator to cool the LS.
Good luck.

I haven't done it, but we have a 4x4 new body style S truck with blown 4.3 sitting so I have researched a good bit.
I've seen a few mentions of the LS truck oil pan being fine except for the diff. A complete front lift kit for the IFS will lower the front diff so the CV axles are in decent alignment. I don't care about doing a lift (and would rather focus $ on the powertrain honestly,) so I plan on doing my own lowering brackets for a tiny amt of lowering of the diff. The Rough Country 2.5" lift looks like it will do the trick too.
The passenger side low AC mount (f-body) requires a chunk out of the frame not unlike a G-body; I think the rest of the S-series / LS accessories compatibility information you'll see for the 2WD guys will tell you what you need to know otherwise.
Exhaust clearance is a different ballgame on 4WD, so plan on trying manifolds and making things work. I don't recall having seen headers for the swap.
