I wouldn't spend the money for the K and S stuff unless you are rolling in dough. Since you already have the type rating, just buy the PASS cards -- it's all you need. The cards cover what is important to SWA and John Pansmith keeps them current with the latest FOM revisions. Systems, limitations and memory items most of the annunciator lights are covered by the cards. There are no flows in the cards but I found that it was easier to learn them in the CPT anyway.
Honestly, you probably don't need to study at all. Enjoy whatever you are doing now.
