Crab to stay over the runway until you have enough altitude to clear
obstacles, e.g., wind sock should the tug drift downwind. The tug
should also crab so you'll both be flying clean, as Tom said. After
you've got sufficient altitude, say 50-100 feet, slide back behind the tug.

No, a slip creates drag. A crab is clean.
