For the reverse proxy, why does it say to use /xbmc-vfs as the location; wouldn't you want the whole site to be proxy'd? I'm fairly new to this, so maybe I'm misunderstanding how it works.

In this case "reverse proxy" means to proxy the XBMC web server behind the Apache web server that you install. If you want to use a reverse proxy for XBMC Video Server itself you're on your own since it breaks quite easily if you do so do the way the Yii framework handles URLs and stuff like that.
