thelt,
it's a fairly straightforward job. you need just basic tools: a pair of jackstands, a ratchet or two, a few different sized sockets, a breaker bar, and a torque wrench. if you have an air ratchet then the breaker bar is a moot point; and the whole process will go much more quickly.
i did the front bushings as well as the end link bushings on my truck a few months back. i ordered a set of grease-able front bushings from energy suspension and they work considerably better than the old, rotted, squeaky stock bushings.
when putting the new bushings on i did use a little bit of general purpose chassis grease to lube the inside of the bushings so they would slide on easier. only a little is sufficient. and make sure the bushing is seated properly in the bracket before you really torque it down. the shop manual says if the bushings are being replaced then the bolts should be replaced as well because there is lock-tite on the threads of the bolt and removing the bolts breaks that seal. i didn't replace the bolts on mine out of shear ignorance, but i'll replace them whenever i get under the truck next.
from start to finish the whole process took me under an hour. but bear in mind i didn't have any air tools, only ratchets, and a big length of pipe as a breaker bar. having pneumatic tools would make the process go much more quickly.
