As for the 'steel' and stones, you're probably best off getting a Idahone ceramic rod, and the 5 piece set from chefknivestogo.
For the knife, I have a carbonext in the 210mm and I really like it, but I will say that I wish I'd gotten a 240mm, for you to consider. Another option is the Richmond Artifex, which I personally would love to order right now to fill my wish for a 240mm, but the pure cost of postage to England puts me off.
