Unfortunately not really. Like I said, buddy up with a 121 pilot to have them walk you through everyday flight operations, 121 regs and 117 rest requirements. If you know someone with access to Jeppesen FD Pro start looking at company charts and the other resources we use on there everyday. Spirit expects you to come in with this knowledge.

I remember reading "everything explained for the professional pilot" before training at my regional. It's a bit cheesy but it is full of good information that will prep you a bit.
