The TravelCard is definitely the way to go. You'll need one that covers four days: Fri.-Sat.-Sun.-Mon. I don't think there's a 4-day pass, so your choices are a 3-day or 7-day.
Should I go for the Gatwick Express separately to Victoria and then transfer to the underground? Or get some sort of combo ticket?
Didn't know there was a combo ticket for the Gatwick Express and underground. If there's a good deal on one grab it.
Any reputable places I can buy advance tickets for transportation now either online or over the phone?
One of those double decker hop on hop off sounds like a good idea -- any way I can buy the ticket in advance?
Probably. Why not just buy when you get there? You can get your TravelCard and probably the double-decker tickets at Victoria Station when you get it. No need for local currency. Put it on your VISA for the best rate.
