Amazedmom, I think I have mentioned elsewhere my two favorite starter books on Asperger's:

Bashe and Kirby, The OASIS Guide to Asperger Syndrome (and the OASIS website (http://www.aspergersyndrome.org/Home.aspx )

Sohn and Grayson, Parenting Your Asperger Child.

These are accessible and practical.

I still think that you should make an appointment soon so that you can have your DD evaluated next time you are in the lower 48. An evaluation will cost you a little time and perhaps some money, but knowing what's going on with your DD given your suspicions would be well worth the investment.
