I am very likely to be in London during the Prologue and first stage. It will be my first view of a real, live, big race up close
Any suggestions for the best way to watch the Prologue? That is, would it be good to plant myself where the riders are starting out one by one, or where they’ll finish, or somewhere midway? Maybe I should start at the start and walk my way to the end, with riders whizzing past once every couple of minutes or so?

We aren't entirely sure where we'll watch the Prologue - as we're staying in the Kensington area, we'll probably end up watching somewhere near Hyde Park I suspect.
We did actually try your latter strategy (start at the start and walk to the end) in San Francisco in February, and it worked out well there - but I suspect it wouldn't be a good strategy for London for 2 reasons:
1) the TdF prologue is longer than in SF (though with the almost out-and-back course the distance between the farthest points would probably be similar), and
2) I'm sure there will be a ton more people around at the TdF, making it harder to get around and to get a good viewing spot (not to reopen the whole "how many spectators were really there at the Tour of Cali" debate, but while the start area was packed and the final hill was packed, in between there were only scattered spectators along the course).
For us in SF, as our first ever live race experience, it was great to see the team areas at the start (riders getting ready etc), and then to see a number of racers actually start the prologue (our decision was helped by the fact that a number of racers we particularly wanted to see for various reasons were starting within the first half hour or so - Basso, Voigt, and of course Gatesie

). We made it within sight of the finish for the last 5-10 riders, so that was exciting too (Leipheimer being the last rider, Rogers and Julich also in the final few).
As for the first stage of the TdF (London to Canterbury), we've recently decided that since we've already seen a race start (Sausalito in February) that instead we'll try to make our way to Canterbury (train early in the morning I think) to see the stage finish instead. Then after that, we have 6 days before we'll catch any more TdF action ...
(and in case I don't get a chance to mention it again here or elsewhere on the forum as I've got a really busy week before we leave for Europe, I'll be trying to put a few updates on the
same blog I used for the Tour of California).
