The Ollie Pop is a good choice, but 145 may be a bit long, especially for a beginner. I ride a 141 and a 143 all-mountain and I weigh 105.
Solid cost-effective bindings: Ride Vxn
More expensive, but higher quality all-mountain bindings: K2 Virtue, Burton Lexa, Rome Madison, Ride Dva
Each binding should come with a sizing chart....
