Phone and book the upgrade now on the 'S' fare and say you are going to use a paper SWU to upgrade. If pressed (unlikely) say it will be a 'Sweet Spot'. Select your favourite seats.
When agent asks you at desk how you are supporting the UG - ask her to deduct 2 x SWU.
If they are not posted there yet, 99% certain they'll let it slide based on your real situation. OR take miles. Not YOUR fault they are not posted by end Janaury. You are a new 1K and can't except to know all this stuff. 
Print out and take this along:

If UA can't be precise on thier own website about SWU deposit date what fault of YOURS is that?
