Answer 1

Right click on your project and go to your build tab. Near the top of the list you can specify your Base SDK. This is the minimum you will compile against. After this your build settings drop down will have the older versions. When you go to make your distribution make sure you aren't using 3.0 cause that will cause your binary to get rejected (as you found out).
