I'm going to London next month. I had my hotel & eurostar tix paid & reserved. Any suggestion on what else might be better to be reserved from the US rather than in London (maybe better price if reserved online, etc). I'm staying there for about a week, planned to go visit the misc. sights (london eye, westminster, museums, etc...) and also plan to use the public transportation. Should I be reserving tickets for the sights & buy the Oyster card in advance?
Thanks!

p.s. this is my first time ever going to Europe
