Better still if you want to save money, use VTEC's own site and book them through there (if you're travelling in a couple of days in advance). If more than 7 days away, you can get them posted free of charge (1st class) or you can collect from Darlington/Durham ticket vending machines (TVMs) for free. Pop your payment card in, take it out (you don't get charged) then input the 9 digit code you get emailed. Then it prints them out.

Believe Darlington Railway Station has ticket barriers although they were open when I went through on Easter Sunday.

Not sure how far in advance they would be booked, especially as we still don't know the date for Lothian Doors yet. Think getting them posted would be the easiest option for me. Not sure who does the service I'd want up to Edinburgh though so I'm not sure if I would be able to use the VTEC website to book them. I really don't have a clue on how to book trains as I've never done it before.
