Transfers / fares from Maglev Train at Pudong Airport to Subway to get to LuJiaZui Street

From the map provided on this site, it looks like I transfer between Maglev train to subway at Longyang Rd. station. I have 2 questions. 1) Do I transfer inside the same station? 2) Do I have to buy a subway ticket or do I just use my Maglev ticket ?

On a related note, can I buy Maglev and Subway tickets by credit card or is only cash accepted for payment?
