Way To "UnSync" With Desktop Manager?

I setup Outlook to sync with my gmail and then it synced with my Curve. Then I found googlesync and gave it a try, so it sync'ed everything twice.

I've decided to stick with googlesync and skip using outlook. I'm in the process of:
1. Trying to figure out to stop making my gmail go to Outlook (I realize this isn't the forum for such a topic though)
2. Trying to "un-sync" everything that the Desktop Manager put ONto the phone so it all comes off and is only on there once.
