I was wondering if you could tell me if my sentence structure using ":" and quotations is correct...

Furthermore, when Howard states: “If I had a spot, I'd slap you in” (54:14), and “everybody has to pull his own weight” (54:30), he uses the aggressive motions of slapping and pulling to emphasize his point.

OR should i structure it like this...
