I'm doing a little reading/studying for the Exchange 2007 MCTS, in between my Enterprise Admin upgrade (which I'm finding pretty dull, hence the mixing up of the studies a bit

).
My application experience is heavily SQL server based and I've never regarded Exchange as anything I wanted to learn - I thought I'd find it boring to be honest.
The thing is, I'm really enjoying this and learning powershell in the process. I've got a few books coming (How to **** at Exchange 2007/MS book for the 70-236 exam) and am watching the CBT's and playing with a few VM's but I just wanted to ask you Exchange super-freaks (you know who you are) if there is anything else you would advise for a keen Exchange n00b?
This is going to be quite important as it's becoming increasingly likely that I'll get several Exchange systems dumped on me and my team in the near future.
Thanks!
