There is an article in the current (or maybe last month's) Peterson's 4Wheel & Offroad mag about doing a an r&p swap at home by yourself. You will need some special tools and a hydrulic press. - but this I'm sure you know.
One thing is, but I'm really not sure, is that certian groups of gears use different carriers, so be carefull. I think that 3.73 may mark the line between one sized carrier for higher gears (lower #s), and the lower gears. It may be that a 4.10 cannot go into the 3.56 without also swapping the carrier. Check this out with someone who actually knows what they are talking about, however.
