Nice! I came in here expecting to add some stuff to your list. Turns out i can't. Good stuff

So is there one convenient location for all of the free stuff in the marketplace or do I have to search things out individually?

Currently no such location on the 360 dash no. Most convenient way at the moment is just to follow the links of the products you wish to download to the xbox.com website, and add them from there.

Voice studio doesn't appear to be available in america

Sorry to hear that. :( Can't use it myself either, but that's because I don't have a Kinect.

Updated OP in any case.

Damn, FFXIII themes not available in the UK. I hate how you can't see themes or gamerpics before you buy them.

good list you could also put actions/achievements that give you free MS points....
