If your driveshaft bolts haven't been off in a while you might wanna try an impact gun of you have one. If you don't, all I've done is use a 13mm 12pt socket (on a 2006 mustang), hit the wrench 3 times and most of the times it will break the bolts loose. If you can get the bolt off even just a little bit, spray some penetraing oil on it (PB Blaster).
As far as a motor swap goes, try to sit down and write down all the parts you will need. In my v8 swap, I hit many brick walls which stalled my swap 3 weeks.
