If I wanted to send audio to the BL600 through some type of profile (A2DP), can I then port that audio out through one or two of the pins?

Answer

BLE devices (including the BL600) are not set up for A2DP or any audio for that matter. BLE is designed around smaller amounts of data throughput and extremely low-power consumption resulting in extremely long battery life. Our BT4xx series supports a form of mono audio and the BT5xx series is designed to support A2DP, HSP, and HFP.
