I am seriously considering moving to Europe (from the States). The
problem is of course the details--its overwhelming all the questions
that emerge. Could anyone recommend a place to get started? A
website devoted to Americans emigating, a book, etc? Any help
appreciated.

If it matters, employment is not a huge problem...I'm more interested
in questions of residency status, tax issues (do I pay taxes there or
in the States, for instance), qualifying for health care, and so on...
again, any help gratefully recieved.
