ISA Learning Material

Anyone,
Is there any learning material on Microsoft ISA server? So far I have only seen one book (ISA Server 2000 by Tom Shinden, Syngress Pub.) on the actual product and this is not due to hit the market until some time in March 2001. I have the product installed on Win2k server w/ active directory and I am haveing some issues. The problem is I don’t know if it’s me or the ISA product as I am no sure on how to do many of the tasks. If anyone knows of any resource material on this new product could they please let me know about it. Please don’t tell me I have to wait until March 2000 I’ll be an expert by then and won’t need the book but I hate to go into things blind!!!!!
