Just a quick recommendation of one of my better local dealers
http://www.hondaofbournemouth.co.uk
The website has a good parts section with nice diagrams of all the parts in the relevant sections along with the prices. Some of the prices are expensive, some arent too bad. They seem pretty clued up, have a good stock in and will post to you. No idea what they are like for servicing as I prefer to do that myself.
