does the 6502 have an internal register for indirect addressing modes to store the pointer?
Yes. There has to be at least some register fed to the internal ALU to allow the effective address to be built up. Why do you need this? Are you doing a state-machine implementation of the 6502?

also, is there an internal register to hold the address for the address bus?
How to answer this in the most helpful way depends on what you are trying to do.
