For (1), a StringSource handles both char* and byte*. See https://www.cryptopp.com/wiki/StringSource. For (2), you generally want a KDF or password-based KDF. See https://www.cryptopp.com/wiki/KeyDerivationFunction. I think the state of the art for {PB}KDF is Krawczyk's HKDF. The HKDF page shows you how to derive independent keys using HKDF. See https://www.cryptopp.com/wiki/HKDF. Going beyond simple key derivation and encryption, you can achieve very good security with an Integrated Encryption Scheme (IES). IES is IND-CCA2, which is a strong notion of security. See https://www.cryptopp.com/wiki/Integrated_Encryption_Scheme.
