All the advice you have gotten here is good. Follow it. If you try and shortcut anything you will have experience on how to do it again next week. Have the flywheel surfaced by a machine shop. I've seen tons of flywheels that look beautiful except for the warp. Don't cheap out on the parts or you'll be gaining even more experience. Stay away from the Chinese junk. Using a pallet jack is asking for trouble. You need to support the back of the engine to maintain the angle to EASILY slip the tranny/ transfer case in and out without dumping the throw out into the bell housing. It's not a hard job but it's a big job that will take you the better part of a day plus machine shop time to surface the flywheel. Working off the ground is a pain in the ass.
