Welcome to the community! Hope to see you around more here. If you have questions you can certainly look through forum threads and make new ones if needed, but lots of the users around here would probably be willing to help if you simply ask whoever specifically as well.
You can change your armatar by clicking the little arrow next to your name in the armor game banner. Once you do that click the armatar button in the Dropbox thing it gives you. Then you just click whichever armatar you would like, scroll to the bottom of the page and click update armatar.
