Spouse of EU Citizen with a few questions

Greetings,
First I would like to say that I have read a lot about Immigration to the EU in this forum and many others, but I find a lot of conflicting information and I have a few questions that I have not been able to answer with all the information I have read.

My story:

I am Uruguayan and my wife is Italian, We got married 18 months ago here in Venezuela. At this moment I have a job offer in Spain and want to know if it would be possible to accept it. My wife has a valid EU passport; my Uruguayan passport is also valid. We also have our Venezuelan marriage certificate with apostille. The job offer requires that I have a work permit in Spain or that I can obtain one relatively soon.

I contacted the Spanish consulate in Venezuela and they told me that I need an Italian marriage certificate.

My questions are:
1) Can I travel to Spain with my wife with one way tickets and enter Spain with the documents I stated above? would I have any trouble entering the country?

2) Can I work as soon as I get to Spain, during the first 3 months, while I get the family member residency card?

3) Do I have to register my marriage in Italy? The Italian consulate here says it could take 5 months, could we just remarry in
Spain to save that time?

4) How long is the process for the family member residency card?


I am sure that these questions have been asked before but after a week of searching, I still have doubts on these questions. Thanks!

if you can make to an eu country than , you can apply for residence card as family member of eu citizen.
if eu citizen is exercising treaty right being employed self employed etc card should be issued within 6 months.
and within first 3 months as you being non eu spouse only can work if your eu other half is exercising treaty rights. as your rights comes from eu citizen. thats in theory but in practice until you don't have a residence card its difficult to prove to employer that you are allowed to work.
