swap the trans, much easier. if it's a 4 cylinder $500, if it's a 6 $1,000 for used transmissions. if it's still not a good deal based on those parts prices then they are asking too much for it.
yes the transmission needs to be removed to replace it. i gave a friend a good front diff to rebuild his blown one and the fresh rebuild blew not long after. i would proceed very cautiously rebuilding a front diff.
if you're still up for separating the trans to try to repair the front diff then go to USMB (maybe some others too - like NASIOC) - they have some folks with some decent info and pictures who have taking these apart before. they don't post often so don't expect a reply but you can find their old threads detailing the trans guts.
