if swapping to an LS engine you may find a keyless option online. their power train control module runs the engine but I think it is the body control module that runs the door locks and cruise control etc, not sure on the keyless start thing. anyway, maybe figure that out before you lighten your wallet just to be sure all the modules will talk to each other and not require more modules to translate jibberish from one to another. ls1tech may be worth some time perusing. I have heard of guys with issues trying to get their cruise control to work with different steering columns and pcm's etc.
nice deal on the engine. if unclear on how long it sat you could boroscope down a spark plug hole to see if there is any rusty spots in the crosshatch cyl walls etc. should be fine though as a reputable shop would ensure the assembbly lube used would hold up for as long as possible.
