Tax advice for U.S. citizen in Spain needed

Hi!
We moved to Spain (Valencia area) in the beginning of this year from the US (NJ), and have spent over 183 days here in Spain this year. I guess we are considered to be Spanish tax residents now.

That said, we have pretty vague idea on the way we should file tax returns this year. I do understand, that the returns should be filed in both Spain and the U.S., but we feel we need some tax advice from a professional, familiar with US/Spanish taxation. My wife is receiving SSA disability benefits, and it is not clear to us, if those will be taxed in Spain or the U.S. only.

If someone knows an appropriate tax specialist, we would appreciate a referral very much.

Thank you!

P.S. We do not have much experience here, in Spain, but collected some knowledge about how things are done, and will be glad to share what we know with people, who are thinking to come to Spain from the U.S.
