THIRDLY, that I obviously wish to apply only one SWU in each direction of travel
First ands Second:
This is should not be problem, regardless of if your SWA's are in OP account or MP account you can use them across airline/metal

Third: Understand your availability challange on all legs, the USA-GRU one is that which you care about, some Y on a 1-2 hour flight is bearable. Don't know your dates but: CO31 (UA Metal JFK) shows W and R on a few dates I looked at, similiar 861 from IAD, concern with both these as old business class seats. If you are coming from LHR - suggest fly direct to ORD and then connect 843, which has dates with availability and benefit of lie flats in business
