Ok I got sick of waiting for the 3.1 update to be pushed my way so I was determined to root. It really is not as perilous as some make it out and the guides and there authors superb.
Two very useful guides
[How To] Root The 3G/4G And Wifi-Only Xoom (Stock 3.1)
This one works great for most Xoom hackers but for some reason ADB would not boot into recovery for me so I used Clockwork Mod and a special recovery file that was sent to me.
[UPDATE][HC3.1] Wifi and 3G! Completely Flashable! No Fastboot Needed! - xda-developers
This one is really simple since it uses Clockwork Mod and there is no typing involved and no ADB or USB connections necessary.
