I have an ipaq1940 which I use with bluetooth to sync with my laptop. I cant remember all the details during setup, but basically you install the bluetooth software on the pc, turn the bluetooth on your ipaq on, get the pc to look for bluetooth devices (open bluetooth neighbourhood or similar, there should be some way of getting it to search). Once the devices have found each other you will have to set up a partnership. Put a pin no. into each if required or as directed by the instructions.
On the ipaq go to bluetooth manager, new connection, activesync via bluetooth, and you should be able to follow the instructions from there. Mine works really well. I also have a bluetooth modem upstairs in my house, so that I can dialup the internet from my ipaq from anywhere indoors. Great if you haven't got broadband or wifi.
Hope the above makes sense. If you need more indepth help try the forums at click here. The are a very good source of info.
