Vulnerable straight draw

One of my first 5/10 hands. Villain is new to the table but sat down with well over 100bb which is very unusal. The other guy is also totally new so no read there either.

Hero - Posts small blind $3
Villain - Posts big blind $5

Dealt to Hero [9s 8d]

3 Fold, Bob Calls, Hero Completes, Villain Raises, 2 Calls

*** FLOP *** [2c 7s 6c]
Hero ?

Whats the plan? I think Villains range is somwhere around AKs-ATs, AKo-AJo, AA-88.
After some thinking a Bet/Call with Villain raising to get Bob out of the pot and then a call on the turn unless an ace falls seems like the best alternative. Opinions?
