I have already booked my ferry for next summer. The Alps look like a fantastic place to take the bike. I managed to get a decent discount by booking early and managed to get a Dover Calais ferry for �25 and the Bilbou to Portsmouth for �125.
To help with planning I have found a link called
www.alpinepasses.com If you look at the maps page it gives links to all the cols in the various region, therefore providing a useful planning tool.
