Look to see what a "change flight" offer is, many times it is cheaper than the offer UA provides in My Reservations.
To get the change fee waived, you will have to call and if the fee is not automatically waived, mention "GG BUY UP"
Since you are on a common PNR, you will not be upgraded separately until the gate if you wait to checkin till you get to the airport. And then at the gate, tell the GA it is one or all.
