I am so confused being presented with various installers in Qt website- open source Qt. Please read my requirements and advice what I have to download in order to start using Qt.

I have Microsoft Visual Studio 2010 running on a Dell Dimension E520 PC. I need to install Qt using Visual Studio as the IDE(Latest Qt open source preferred). There are various Qt links such as Qt creator, Qt add-in for Visual Studio etc. How shall I go forth to doing this? Please help.
