If you spend the money to buy a swap kit, I think I'd use that money towards a MII or similar kit. That is a far simpler project and all the sheetmetal just bolts up like it did originally (except maybe triming the inner fenders but I can't sweat to it). No messing with mounting the bed, cab and all that either.
The S10 swap is a lot of work but it can be done pretty cheap if you buy the whole S10 and part it out to recover some cost. But like I said if you have to buy a swap kit to do it, put the money toward a MII kit or Scott Danforth's IFS kit which uses GM G-Body/S10 factory suspension parts.
Here's a pic I found on the web of his IFS crossmember installed. I think it works with all stock S10 suspension parts.
