Wow.....quite a list of 'things to do'
Firstly, hire a car!, public transport here is expensive and unreliable, especially if you are going to spread your wings a bit while you are here.
Accomodation outside the capital is pretty good, there are thousands of good quality B&B's (bed & breakfast) to stay in, as well as the ususal chains like holiday inns, Ibis, Travel Lodge etc
Your best bet would be to go to a tourist office when you get to London. They are pretty good and will have the latest info on accomodation.
However, when you sort an itinerary out, let us Brits know and I'm sure there will be some specific recommendations made for the town you are visiting. Who knows?, you might even get a guide!
Whilst on your grand tour, why not call up Triumph, go to Hinckley and tour the factory....who knows you might even see your BRG being built!
how cool would that be. They welcome visitors, but the tours are by appointment i believe. Peter Clark is your man to speak to at Triumph.
Other places to visit....hmmmm, that would depend on what you are in to. If history is your thing then we have it all here. But if it is more nightlife/social scene, then the major cities take some beating.
If you pin it down a bit more I'm sure we can help you a bit better.
Cheers
