Directory Structure of vB 4 Suite
 

I could not find the answers to these questions via a search. Maybe my search terms weren't good enough.

Before I make my final decision of going for the vB Suite* I need to know its directory structure. For example* I have my vB forum in:

mydomain.com/forums/

Where will the various suite components go? Will everything go in the forums directory and then say a CMS file placed at mydomain/com/CMSGoesHere.php?

If at the end of vB 4 Suite* I decide I want the vB 5.x Forum Only* will it work with the then old vB 4 CMS? Will an upgrade to the Forums Only actually work?

If I get the vB 4 Suite now* will the vB 5 Suite be made available to me at a discount from the full price* since I'll be upgrading to the new version rather than buying it new?
