In my line of work, I meet alot of folks with their own jets. I fly commercial.

That puts me at a bit of a cultural disadvantage. Fortunately, Bombardier Flexjet publishes a list of ten Rules of Jetiquette for first-time fliers on privately owned jets. Business2.0 provides a summary.

The longer piece, summarized in the April, 2003 issue of The Atlantic (Not online yet, but hopefully the piece will be here) offers:

Observe the boarding, seating, and drop-off hierarchies… The captain or the owner of the aircraft will normally greet and escort you to the plane. The owner is usually the last to board. The owner will usually sit forward facing and as close to the flight deck as possible, depending on the layout of the aircraft. This way, the owner can more easily communicate with the crew in the event of in-flight destination changes or other issues that might need to be adressed…And remember, the owner of the plane always gets dropped off before his guests.
