Thank you all! I've constructed a study checklist based on your information.

My background: Just 95 short on the cross country for meeting all the experience for 61.159 ATP and a small amount of King Air experience. Reading the previous posts on this thread have got me puckering.

I've been practicing checklist and immediate action items with a detailed Dash 8-300 on FSX and plan on making flashcards for every switch in the aircraft, on and off. I have no 121 experience so I think company Ops Specs and legalities are haunting me the most. It seems a lot of curve balls on tests can be thrown from those subjects. For example the "can we depart? can we land?" questions.
