Agree with the idea about lots of small bills, as indeed change seems to be at a premium.
If you are going to be traveling in the area by car, it would pay to be aware of the gas station scam which is detailed on the loco gringo site. Too much to go into here, but if you do a search on locogringo you will hear all of the variations and the ways to combat them.
I haven't used all the maps you mentioned, but would like to add the Mundo Maya map of the Yucatan penninsula. We bought ours at Chichen Itza, but I've seen it other places as well.
I think that all of us have run into the gas station scam and the toughest thing to find in Mexico is the 10p coin. I always carry a bunch of $1's with me for tips.
I haven't seen the Mundo Maya map, but will keep an eye out for it next time we are down there, which may be pretty soon. VivaAeroBus is starting daily service out of Austin to CUN next year with regular prices around $200 rt. The Can Do maps are especially strong on hotel, restaurant, and attraction locations/web addresses. Makes trip planning a breeze.
BTW, if you liked CI, you have to go see Ek Balam! Just north of Valladolid off the road to Rio Lagartos (sp?). It is literally rewriting all the books on Mayan art.
