Have you tried playing keyboard and mouse yet? I remember learning to circle-strafe with a mouse after being a purely keyboarding shooter with DOOM and Quake.|
At first it seemed like an /impossible/ interface and I spent more time looking at floors and ceilings than I spend looking where I was going, but once it clicked (happens faster than you'd think) there was no going back. Suddenly Quake and Quake 2 became utterly different, amazing beasts to play.
