In what order should we walk back up the Aisle?

On the way up the aisle, after the ceremony, the bride and groom should lead, followed by Bridesmaids and Pageboys, the Best Man with the Chief Bridesmaid, the Bride's Mother with the Groom's Father and then the Groom's Mother with the Bride's Father.

The Bride and Groom start off dancing together, then the Groom should dance with his new Mother-in-Law, and then his own Mother, while the Bride dances with her new Father-in-Law and then her Father.  The Best Man should join the dancing, with the Chief Bridesmaid, when the newly-weds first break apart to dance with their in-laws.  The rest of the Ushers and Bridesmaids are also invited to the dance floor at this time.  Once the song has finished, all the guests are invited to join the party on the dance floor.
