Good questions. As far as jackstands go, the bigger the better. You'll be glad later if you choose oversized jackstands today.

The engine will be easy for 4 guys to lift into a truck. It can just sit on its heat exchangers. The rear of the car needs to be raised pretty high (like about two feet at the torsion tube covers), but it's stable at that height if you use the herculean jackstands I'm recommending.

The balance point is between #2 and #3 cylinder, roughly. Release the engine mounts first. Lower the engine so that it is parallel with the ground, then release the tranny mouts. The engine will balance and slide right out.
