You might also suggest to your manager to get you registered for some courses, such as the IBCA Compliance Institute, which will give you a broad, but comprehensive overview of the regulations affecting the deposit side.
If not, I would recommend focusing your efforts on what I think are the top three regulations for deposits:
Truth-in-Savings Act - Regulation DD
Expedited Funds Availability Act - Regulation CC
Electronic Funds Transfer Act - Regulation E
as well as Regulation D (reserves) and Regulation Q (interest on deposits)
