[quote=Dogboy][quote=greddawn]What do each of these cam cleats go to, and are they necessary?

The lance cleat, as suspected, is almost certainly for the jib furler line to take the place of the crappy stock cleat.
The other three cleats, your guess is as good as anyone else's. Most likely they were rigging controls for a spinnaker or positive mast rotation device, but really could have gone to anything.
They are certainly not stock and certainly not necessary if you're sailing the boat in it's stock configuration (mainsail & jib only).
