I've attempted to solder one of the boards and had an issue with the bluetooth RN52.

1. Im guessing that the pads on the bottom are just surface connection meaning that they don't get soldered and make a connection solely by the surfaces touching together. True?

Yes. Those pads are designed for soldering using reflow method. Since we are not doing that, they can be left as they are.

2. Is the drag soldering method the most efficient method to solder this piece (RN52). The leads on it are different than any other piece, such as the headphone jack.

Yes. I have made quite a few modules now and have found the drag method to be the most efficient for soldering RN52, MCP2515 and the small CAN transceiver (SN..)

Also, in the mouser part list there wasn't a 6 position header, is this no longer needed for programming?

The header part is still needed. I've bought a batch from the local electronics shop. They sold them in strips of 40. In my case they are "breakable", so I can break off the length I need for FTDI, Factory Reset and UART connectors respectively.
