You can do it on the same level if you want, it's probably the most efficient way. Just go out of security in A, walk through the CI-HALL to C and to your gate. There are a few stairs though as the A/B/old C level is lower than the new C level. And if you want to use the lounges near C13 you will have to go upstairs for the lounges.
Bus as said before a lot will change until mid-next year in FRA, and the gate assignments for flights change on an almost daily basis anyway. There's a very large changes that the Vancoucer flight arrives or depares in the B pier, and intra-Schengen flights can use all lower A gates as well as the bus gates in B.
