Have you done a 4.0 Engine Swap?

My 88 Wrangler has a worn out 258 six w/5 speed. Rather than rebuild and continue with carb and emission system woes I am thinking about a later model engine. Will the 4.0 six bolt in, and what problems will I have? What year engine should I look for? What components outside the engine (computer etc) do I need to make sure are included with the engine purchase? I have the weak transmission and have some transfer case woes, so what about bolting in the entire package... engine, transmission, and transfer case? Will the driveshafts connect without modification?

So this can be done, correct? What else would be needed to convert 258 w/auto to a newer 4.0 FI with auto?
