Hi everyone -- just wanted to report back.
I got the Panini, as projected. Chose egg and mushroom, and it was really quite nice. Crew was great, and we flew a nice little Fokker.
I got into the lounge (despite huge suspicion about my prontout; even though the UA*G was on my boarding pass, lounge attendant checked status with UA). Lounge was pretty disappointing though -- just snacks, really -- I was hoping for more breakfast foods. Been spoiled by BA...
Anyway, thanks for the responses.
