Yea its kinda simple.... Just pull that pin on the top out and the pads will just pull up throught the top (use a pliers to pull them up). Then just drop in the new ones and put the pin back in and your good to go!
Probably a little more to it then that, but its close. Its not really all that hard to do, just getting the new pads in and lined up to put the pin in can be tricky. And if things are rusted and stuff, could make it harder. You might also have to take the whole caliper off and use a c-clamp to press the piston in (cant remember been a while since I last did one).
Should'nt take you anymore then 30 min total either way. Good Luck. Have fun!
