Need some Clarity about Moving to Spain

Hello - I am an American living with my wife in Brooklyn, NY. She is originally from Madrid. We are moving to Spain (Barcelona) in January'09. I am finding several things confusing about what it is I need to do to get myself legally 'in the system' there. I have a list of things I should do, from a book titled, 'You and the Law in Spain' but, even this is a little vague at times. I am wondering if there is anyone out there who has recently gone through this process and would like to share their experience with me?

My understanding is, that since I am married to an EU-Citizen/Spanish Citizen, I have the right to work but need to apply for the residency permit in order to obtain a work permit. However, in order to obtain the Residency Permit there are several things I need to provide to the Spanish authorities, some of which are showing that I am working! Basically it seems you can't have one without the other...

Of these things the most confusing is the following:

1. Proof of Financial means, this is stated but no details are given in to what they mean by financial means....
2. Medical Certificate (I would assume there are specific doctors working with the Spanish Government)
3. Medical Insurance - Book States ' Your private medical coverage must be contracted with a company which has an office in Spain'
4. Book States - 'Statement from your Spanish bank showing that your income is arriving from abroad and being deposited in Spain'

your comments are appreciated
