I've often used a sneaky method of getting in the First Class Lounge at Doncaster when I've had a while to wait late at night. When I was on child tickets, and FC fares were 50% less than the adult fare, I always bought the mega-cheap Doncaster-Hull FDS, which was only about £1 more than the SDS! As this is officially a walk on ticket on the GNER route they couldn't refuse me access to the First Class Lounge, despite the fact that I was on an £8.50 ticket 
I didn't actually think there was any YP discount on first fares! Thanks for setting the record straight there on the Virgin Advances, I'll remember that!
I didn't need a passport when I bought my YP Railcard, just a passport photo and something with proof of address (bank statement etc.). You could use your passport as your ID though if you wanted.
