@xcrogers - congrats with the move. I ride in regents park often on my way to work and I'm sure you'll standout with a Dimond! I haven't seen one here, yet. Big Rapha cycling groups on Thursday mornings (which I see but don't participate in much). I think there were 20-30 of them this morning (sunny weather = fair weather cyclists).
I would 2nd bespoke cycling who do Retul fits. If you've done a Retul in the past, you can give them your coordinates and ask them to just adjust you (should be way cheaper). Plus, they have 3 locations in central London which should be easy to get to from your work or home.
I have had multiple fits from Ben Hallam, he's been there for years and done a ton of fits:

ben@bespokecycling.com www.bespokecycling.com For shipping a bike to European races, I've seen these services:
http://www.shipmytribike.ie/ (lots of races)
http://www.raceforce.co.uk/ (newer service)
If you can afford it, traveling is soooo much easier to races without the bike hassle. It's been a huge time saver for me to travel with a baby to a race. Fly Saturday morning, register, park your bike, sleep, race, give you bike back, sleep, fly home (with only a few bags).
Good luck!
