When we go through customs, collect our luggage and get to the arrival hall will we end up in the same place?
No. T2 and T3 have separate arrivals halls.
T3 and T2B are different buildings about 500m apart. You can walk between them.
where is the best place to get together and get the transportation we have arranged for.
That depends what transportation you have arranged and where your transportation is going to be waiting.
You might want to meet somewhere central.
