You can now vote for which user presentations you would like to see at the Developer Summit in Palm Springs in March. The voting is open until the 7th of February. I had a quick look through now and it looks like most of them are related to ArcGIS Server.
If you would like to know more about how to use Visual Studio more effectively I would recommend this session: “Visual Studio 2008/2010 Tips and Tricks”. It has been prepared by myself and my colleague Rob Clark.

You can find all the presentations here: http://esri.force.com/devcon2010
