The numbers return! - Hurley's birthday party

Hurley comes home to with some food from Mr. Clucks (I guess some habits are hard to break) and finds a coconut on the floor in his home. He also hears whispers and grabs the golden Jesus statue to defend himself until he realizes that the whispers are all of his friends waiting to surprise him for his birthday. The DJ at his party has the Geronimo Jackson album next to his turntables (this makes two episodes in a row where we've seen the album cover). In the same shot there is a boy in the background wearing a jersey with the number 4 on it, one of the numbers.

Hurley's dad, David Reyes, takes him to see his birthday present which is the car the never finished when he was a boy. Once again we see the keys to the car are on a rabbit's foot keychain. He gets in to take if for a spin and finds the numbers staring back at him. 481516 on the odometer and 2342 on the trip counter. Hurley freaks out and then takes off down the street. Is this event what led to his return to Santa Rosa Mental Health Institute?
