Not to me. Putting aside the hour you'll spend going back and forth and dealing with the extra security, what are you going to do there? The JetBlue terminal offers wifi, power outlets, reasonable F&B options and good views, depending on what you want to see or where you choose to sit.

Yes.
Also, the standby/same-day change option thing is a good idea. Standby is free for the flight immediately prior to yours. Or confirm on anything earlier for $50, assuming the seats are open.
