If you'd like a little light reading, I recommend the Skyway code - pretty much the only human-readable document that the CAA have ever produced (I might be a little harsh). Nothing to do with converting your license, just a good place to get a feel for the differences between US and UK.

Redhill is my local airfield, so I'm glad @JollyRog recommended it.
