The axle isn't hurt because the wheel bearings don't touch it. Click my signature link & look in the Brakes & Hubs album. It shows everything you need to know, but you can skip some of it. You probably don't have auto hub locks, so skip those. You have the oldest style of caliper with a bolt on each knuckle to hold the keys in, so skip the pics about the rubber-filled keys and the floating calipers.
If you plan to do this on the side of the road, in addition to regular wrenches/sockets/ratchets, you'll need a set of inch hex keys, metric hex keys, torx drivers, hammers, a large prybar, a long drift (punch), outside snap ring pliers, rags, good EP grease rated for disc brakes, a bearing packer, lots of rags, needle-nose pliers, mechanics picks, a piece of cardboard, a trash bag, more rags, lug wrench, jack, jack stand, reflective triangle, & a flashing light. Also, it requires a special spanner socket with 4 teeth to remove the wheel bearing nuts, which look like this
