Paul 5 - thanks for your input too. Do you suggest I start off just working on the R,3,5 chords first? When starting to add the 7ths would you always drop the 5th instead of the 3rd?

To be honest, R,3,7 chords are easier to finger than r,3,5, so you might want to start there? As regards always dropping the 5th, it's not a rule, it's just that once you start adding extensions (7ths, 9ths) the fifth becomes less important. The 3rd tells the ear whether the chord is major or minor, and the 7th adds more interest by being close to the root note (even though it's up an octave) and causing some tension. The 5th sits perfectly between the root note and the octave, so by comparison is a bit 'vanilla'.
There's certainly no rule that says you have to drop it, it's just that it's simply not adding as much to the sound of the chords as the other notes, so it's often left out just to make the chord simpler to play.
