remove plumbing lines (water, fuel, oil), disconnect wire harness (label if needed), oh yeah disconnect battery first, take off throttle cable and any other misc stuff connected to the motor. Take off starter/four bolts/studs holding the motor on. Take of any motor mounts. The motor will not fall out, it will stay put on the trans. Get your buddy over (or floor jack) and wiggle it out. Subies are not that heavy. I used to pull mine out by myself. Two people helps, but not needed.
For the trans, take off CV/axle, slave and shift rod. Put a jack under it to hold the weight and unbolt nose cone/mid mount/hanging mount. Slide that effer out. Clean all the CV grease so you don't get it everywhere.
Go in the house, get your checkbook........
