Now, something I'm having a hard time understanding is what cam tensioning is? I see the cam tensioner part on VexPro and can't for the life of me understand its purpose.

With a slotted clearance hole for your shaft, an adjustable cam can be turned in order to "slide" the Versablocks over, in small increments. Since chain stretches, the notches in the cam push against the versablock to tension it. You can check out a cam tensioning system in action on just about any chained WCD, and some belt driven ones. But yeah, just make sure the clearance slot exists.
By the way, go check out Adam Heard's user signature, he has a link to all of 973's available CAD, which include the west coast drives that I learned about all of this from. I can't recall off the top of my head if all the files include an example of cam tensioning, so you may have to check out a few of them.
I'll post back with some pictures.
Edit: This thread in general will help you out a ton -

254's media gallery isn't working for me right now, otherwise they have some of the best examples for all this.
