We have 4-day Military Salute Tickets, we are staying one night at one of the Disney Springs hotels that offers the 60-day FPP and early/late entrance. Then the rest of the nights we are staying at SOG.
Do you have a Disney experience account on-line? You are able to customize the bands up to 30 days out of your trip date when the final payment is due - then they will send you the bands
We are also staying at SOG this October. I would be interested to hear how your trip goes! Still learning about the Magic Band info myself as I think I have to purchase and set up since we are not staying at an official resort.
Are you getting them as part of your resort stay or are you purchasing them? If they are part of your resort stay, they should come connected. If you are buying them outright, there will be a code you can link to your MDE under the Magic Bands & Cards tab.
Note for non-Americans. Disney will not ship Magic Bands out of country. (well at least not to Canada) You have to pick them up at your resort check in desk.
