So I went ahead and ordered a small selection of books separately, instead of a kit...that way I didn't pay for another FAR/AIM, a flight bag, and was able to put in some other books instead.

I got the:

FAA Pilot's Handbook of Aeronautical Knowledge
CFI, Comm., and PVT PTS books
Gleim CFI flight maneuvers
Jeppesen flight instructor manual
Gleim ground/flight instructor test prep
and the FOI prep I already owned.

Altogether, relatively inexpensive and should give me a strong foundation and lots to do for the next month or so.

Thanks
