I, too, bought a 50 pt resale at BW (for the 11 month window). We now have two membership #'s, two use years, two separate contracts, and get two copies of everything! The timeshare store, nor Disney had any knowledge that we were already members. Frankly, I don't think they cared because it had nothing to do with our new purchase.
So, I guess to answer your question, yes, they will get "normal" member treatment.
As for another one of your questions, I spoke to my guide recently about Disney using it's FROR (We were thinking of reselling that 50 pts and getting BCV instead) He said that doesn't happen very often. So, we bought 150 at BCV anyway!
