Here's a few things I'd do differently than the Pirate4x4 write up...
1) You'll probably be at home, so use a bench vice to press in and out the bearing caps.
2) If you're going to use a hammer to bang the bearing caps on or off, support the area around the cap opposite the one you're banging on with a socket, such that the bearing cap will fall into the big socket, and the sides of the socket will support the "ears" of the axle shaft.
3) Clean up the inside of the "ears" on the axle shaft (where the bearing caps go into) with sandpaper so that there are no burs. Burs, nicks, roughness, rust, etc. will make installation that much more difficult.
4) Make sure the clips that retain the bearing caps on "really in". Sometimes they look like they are in, but are almost there and will pop out when you need them most.
5) If you can use 3/4 clips, instead of the 1/2 clips, they are much better.
Also:
1) Read the instructions that come with your u-joints. For example, my Spicers said not to add grease and to be very careful about keeping each cap matched to the bearing end it came off of. Of course, if you are using greasable u-joints, grease them after installation.
