What precisely, is a bluetooth GPS receiver?

Or for that matter, a GPS receiver? Please be precise. I would like to use one with my Sony Ericsson K800i for sat nav, but I'm not sure if this is what I want.

I guess your phone has the software for GPS navigation. What it lacks is the hardware, or GPS receiver, to make it work. The GPS receiver detects signals from GPS satellites and transfers the information to the handset via Bluetooth, magically turning your phone into a SatNav system. I have a Nokia phone and bought a GPS receiver module for it just the other day and it seems to be working fine so far.

Assisted GPS

With Assisted GPS technology, GPS Data (ephemeris data) will be downloaded from an A-GPS Server through internet and transferred to the GPS via USB. This will greatly reduce the TTFF since the positions of the satellites are known. The downloaded GPS data will expire in few days if the GPS is not being used. If GPS receiver is being used on daily basis, GPS data will also be downloaded from satellites.
