A/C compressor replacement in '95 Tracer/Escort

Hi guys. My A/C comrpessor needs to be replaced - looks to have seized an internal bearing... I turned it on the otehr day and it was really loud, looked at it and the pulley was smoking, hahaha - this sems to have cooked some of the outer/pulley bearings, 'cauise now it makes quite a racket just getting pushed by the belt.
So for the time being it's been bypasses, just put a belt on for the no-a/c vehicles.

Anyhow there are 2 reasons I bring thsi up.
1 - anybody got a compressor laying around? Otherwise its off to the boneyards or eBay.
2 - anybody have any advice/suggestions/tricks with replacing this thing? Looks easy enough... but I figure I shoudl go ahead and flush the lines, replace the drier. Anything else while I'm at it? Car has 205k miles and is worth about $500 so minimal investment is preferred.
