Getting started with understanding when and how to employ Forefront

Hello,

I am a BizSpark member and setting up a team software development environment.  It appears I will have to open my Team Foundation Server to the outside for certain aspects.

1) As I have been studying how to set that up I came across Forefront.  I don't really know anything about Forefront and I am first wondering if this is something I need to install/engage for my situation.

2) Assuming I need to start working with Forefront I would appreciate recommendations for books/tutorials that can get one up to speed quickly and efficiently.

Thanks.

Best Regards,

Alan
