Help!! Our Marketing dept is moving to MAC

I do high-level PC troubleshooting, networking and server support here for my company, and I’ve just been informed that VP of our Marketing dept wants to move to MACs. I can’t say that I blame them. From everything I’ve ever heard about the MAC OS, it’s nice & stable & handles graphic intensive applications very well.

My only problem is, I’ve NEVER worked on a MAC… One would assume that the hardware works basically the same, except for it’s interface with the OS. I need to VERY QUICKLY learn the MAC OS — and how to integrate it with our Exchange/Active Directory/W2k workstations/W2k3 Servers.

So… any resources, good books, classes, whatever… that you can recommend, would be infinitely appreciated.

Thanks!!!
