If your goal is to be able to do this trail-side (as in, you got a flat, on the trail, and you need to repair it), then what you need is: 3 Motion Pro tire irons, a tube, a large crescent wrench, a 12 & 13 mm box end and a pump. That's what I carry for my rear tire tube changes.
If you're just looking to watch someone do it, I can just ride my XR over and show you what I carry and how I do it with the tools I carry on the bike.
Soapy water or baby power makes things go much easier. Most of us carry baby power on the trail for the changes because it helps get the tire on and off, helps set the bead and helps the tube stay cooler in the tire (due to less friction).
I don't change out my tubes, because I change tires like I change underwear. However, if it's been a long time since the tube has been changed, then you can get a new one, and keep the old one as a spare if you like.
