The Audio Chord Wizard is a great tool for handling this situation; I do it all the time. Once the audio is in the ACW, you can hit the (f4 or f8 key, I don't recall offhand) on beat 1 of every measure and it will automatically create a tempo grid that follows your song. As John suggested, if after bringing it back into the song page it doesn't quite get all the chords right, be sure and edit them before you start generating Realtracks.
