You CAN do your #1 request on the Melody and Soloist tracks. The command is much as I had guessed:

Melody menu, Edit Melody Track, Transpose, Transpose Melody Only, click the radio button Part of a Song, and specify the range of bars and the number of semitones.

Soloist menu, exactly the same way.

However, if you have a RealTrack, that's a problem. When you wrote "say I have a piano track, a guitar track and a string ensemble track" you didn't say if they were MIDI.
