If you want to learn how to rig, you can use carbint's tutorials on youtube. They might seem quite complicated but, so far, they are the best ones out there. They are complete and properly show you how to make a functional rig. You will of course need to eventually fix some weights manually, bugs and add more stuff on yout own. I recently started doing that and it's not easy.... it requires trial and error for sure.
