Needing to obtain my public passenger chauffeur license but wondering which info I need to know...?

I have just started driving a taxi part-time to bring in extra cash and need to obtain a public passenger chauffeur license (I live in Indiana) but there's nothing in the Indiana drivers handbook that tells which information is relevant specific to the PPC license. There's a lot of information to wade through in the booklet, and I hate to go over a lot of stuff that I won't need to know just for the PPC. Any suggestions or recommendations would be appreciated.
