the CP2102 appears to be a usb to uart bridge, similar to the popular FT232 from FTDI?
where does bluetooth come into play here?
you should have no problem going PC -> bluetooth -> bluetooth uart (aka bluetooth serial port) -> pic
many bluetooth serial ports are controlled via a more or less standard AT command set via their uart interface - your microcontroller may have to tell the radio to turn on, or become discoverable, as well as manage any PIN code exchange (may not be required)
there aren't any drivers required - if your PC has bluetooth capability, the drivers are already installed.
