Need advice! EU & Non-EU

Hello, everybody!
I need some advices, can anyone help me to understand " What should I do to make it right? "
Situation: Im EU-citizen,Hungary, my husband is non-EU. We want to move in Spain.
What do I need to get a Residence permit to me and my husband. He have a visa 90/180 days.
We came in Spain, rent a flat. After that I should go to take the NIE, getting NIE.
Take the following documents to the Extrahjeria:
1. My passport.
2. NIE
3. Rent contract.
4. Marriage certificate or paper from my embassy that my marriage is valid.
5. Husband's passport
6. Medical insurance (?)
7. Foto's
8. Proof of having sufficient funds. Bank statement is enough,if it will be translated in spanish? And how much money I need to show? And I have a freelance job in Russia, with contract.
Do I need to bring it too?
