Two questions on rooting

[Arjoma]

Hi everyone!
I just wanted to ask a few things referring to my TF101.
Fifa 12 doesn't work on it (strange graphical errors, even at the downloading dialog). I think Chainfire could solve that.
So I'd need to root my tablet. I've rooted my phone and installed hundreds of ROMs on it, I am just not so sure with my Transformer. I think I know how to do it, just some questions about it:
If I root, will the ICS update still arrive as supposed?
And if something should go wrong, I think I can still flash a clean official Asus firmware file to get it working again, correct?
Tanks!

Your transformer isn't much different than your phones, other than the ROM's are different and the way you go about rooting is just a bit different, but still very similar. So you can transfer a lot of that knowledge over as it is still basically the same android system
