would it be possible to use a icon the is also used on aim? Like off the site ballericons.com. There some biking ones i would like to use on there but dont know how to get them in

It should be. Just right click on the icon you want and save it to your computer. Then go to your control panel, edit options, and use it as your Avatar. It has to be 64x64 pixels or less though. Hope this helps.
