Address Book hope:
On the Dare, go to Settings and Bluetooth and tap to TURN ON, then tap the menu icon (lower right) and then tap Discovery Mode and tap On.
On the Mac, go to Bluetooth System Preferences and click the "Show Bluetooth status in the menu bar" in the lower left and close the window and then in the bluetooth menu bar icon, select "Setup a Bluetooth device...", then pick the "Mobile phone" radio button and Continue and wait for it to find your phone (first by MAC address, then as "LG VX9700") and click Continue and Continue.
Then back on phone, tap Yes to accept pairing, and type in the Passkey on the Mac's screen (8 numbers) and tap OK, and then tap either always connect or ask (I say always connect--you'll turn off discovery, and only have Bluetooth on when you need it--to save battery, yes?).
Back on Mac, uncheck to access the internet with your phone's data if you don't have a data plan on your phone (as I don't, the whole reason to pick the LG Dare over an iPhone or Samsung Omnia) and click Continue and Quit.
Next you'll want to export all of your contacts as vCards: open Address Book and select all (apple/command key + "a" or click on the first contact, then hold Shift and click on the last contact), then right click (or hold Ctrl key down when clicking) and select "Export vCard..." and save that master vCard to whatever place (e.g. Desktop). OK; this part isn't true: you'll have to do this one at a time (ahhhhh).
Next, in the Bluetooth menu bar icon, select Send File, then browse to where ever you just save the vCards files to and select all of the files (i.e. apple "a") and click Send, then pick "LG VX9700" and click Send--hardly a sync, I know, but at least a way.
For iCal, you'll have to go third party and convert each .ics entry to a .vcs (vCal) and then you can do the same as above, but nothing native.
