I did this too recently. There's a thread on here somewhere I posted about it. Anyway, I got the drivers glass out really easily, I even took it out and refitted again twice (don't ask) and no problems.
So I tackled the passenger side with confidence and cracked it on first attempt! For whatever reason the passenger side is harder to remove in one piece, I don't know why... maybe its just coincidence.
The LED puddles do look good though, so it was worth it... I think!
