...will everything start back at 0 once I resume my Campaign?
GuitarZan, when you re-start your campaign by submitting your credit card again, everything re-starts from where it was. So, no, you don't start back at 0.
However, it is possible that the competitive landscape may have changed a bit in the interim - as nothing stays the same for more than a second or two.
So, I'd continue to monitor and adjust as you always do, and I think you'll see things return to where they were.
