Motor mounts are easy: you can buy new OEM ones through dealerships like
http://www.mossyperformance.com and
http://www.courtesyparts.comOr, you can buy aftermarket insert from Energy Suspension and Prothane. Either way, expect to spend the better part of an afternoon replacing the mounts. Maybe longer. It can be a tough job (read: long) for the inexperienced.
Axle: Buy a remanufactured one from AutoZone, PepBoys, etc. Easy install if you have the right tools, maybe 1/2 an hour to 1 hour.
Remote: I have no clue. Sorry.
