Assuming that the front end sheet metal is intact, the engine/transmission unit will be a convenient lump to install first. Lining up a heavy SM465 is not a fun job, especially lying on a garage floor. Did that, won't do it again. The transfer case install will be easier- not a fun job, either, but more manageable. A good hoist (1 ton or better) and a good trolley-type hoist attachment will work wonders- even if you do it by yourself. If you've got the front clip off, it is a very easy job (comparatively), and if time is not a big factor, worthy of consideration. Good chance too clean/paint/detail/rewire the engine compartment, too.
