That's a great detailed itinerary for Tailand. Good job. I personally took a different road in Thailand. I spent few days in Bangkok where I of course visited Koh San Road :D and then head up north to Chiang Rai where I spent 3 months working with a Children Right's NGO.

Thailand is just so wonderful because it offers opportunities for every type of traveller!

I just wrote an article about how I almost got burned in Thailand. Maybe you enjoy reading it (づ｡◕‿‿◕｡)づ
