Maps available on the Camino

I am just one week away from flying out of California to get to Pamplona and start my camino.
And of course, I'm wishing for more time to plan. Is there ever enough time, or too much?
While I have a general route planned, any additional information, such as better, lesser known bike routes into and out of towns like Burgos, would be a welcome addition to my tool bag.
Anyway, I saw a recent thread referring to both the Michelin maps and a Jakobs Radweg guide. I've been unable to locate the Michelin maps locally. And, I believe it's too late to order these before I leave, so is it possible to find either of these in Pamplona or along the Camino Frances?

Thank you MsPath. Again, your advice has been very helpful. Caminoteca will be one of my first stops upon arrival in Pamplona.
