Done to death I know, but I have a few questions that I don't think have been answered.

If I use WMP to sync I know you can setup automatic sync, but it appears it wants to copy all of my photos and videos from my PC onto my phone which I don't want. Is there anyway to configure the sync so I can decide what I want to be synced from PC to phone?

The Windows Phone desktop app. Does this work at all? By that I mean does it sync music bought on my phone onto my PC?
