I can help here, did a bigger group trip earlier this year and our friends were in a 2BR. If I’m not mistaken there are 7 2BR suites, 2 on floors 1-3 and 1 on floor 4. See below for the locations (this is the first floor, as an example):

The 2BRs closest to the lobby are
MATERIALLY more convenient to the lounge than the ones on the ‘far end’ of the resort. IMO you definitely want to request “close to the lobby” if you book a 2BR… unless you want to be in the other location, which is a closer walk to Epcot. Otherwise that’s a pretty decent treck to the lounge. The 2BRs close to the lobby are an excellent location for daily comings/goings, IMO.
Exact balcony configurations vary by floor, some have full-sized real balconies, some have smaller or Juliette ones… a little YMMV.
Pre-COVID Disney suites didn’t generally follow general public or AP discounts - you’d be lucky to find a 10% discount, if you could even find one. They got a little more generous with suite discounts for a bit after reopening, but lately it seems like it’s pretty much been full price. I’d mentally expect to pay rack, and anything else is upside.
Yes, two bathrooms.
Let me know if you have any questions, happy to help.
