London A-Z by massuc
Buying the London A-Z map guide was one of the best investments I made. It saved me so many times when I took a wrong turn. There is no need to buy them ahead of time, they're available in every souvenir and convience shop in London at a fair price. I think the spiral bound editions are best, but I got around well enough with my paperback edition. This book also includes a London rail map, a cinema and theatre map, and a Tube map.
