The version switcher is so you can switch between 4.08 and 4.09 and also so you can turn the mods on or off.

You do not need to install 4.09

All mods should work with both versions (some custom maps need 4.09 to work though)

The switcher is there because some servers use 4.08 and others use 4.09
Not all servers allow mods so they need to be turned off to get in
