There are only two motor mount to deal with, and the driver's side is a bit more difficult to do simply because of its tight confines. The crossmember has an access hole to get at the lower driver's side lower bolt (or nut, I can't remember). Because of this, if you drop anything during install or deinstall, you run the risk of parts rolling into the crossmember hull...then it's bolt fishing time!
I usually duct tape around the area so as not to offer another path for parts to escape!
In either case, you must raise the engine slightly (the wood plank across the oil pan is a good tip as it relieves the stress and weight of the engine from being concentrated on the jack point). Makes the mount swap easier too.
