If he had a visa and he was admitted into the US, he can now adjust status through you (provided that he has no criminal history that would prevent an adjustment). You should file I-130, I-485, I-131, and I-765 all as one package. With those forms, you will have to pay fees only for I-130 and I485; the other two forms do not cost you anything if filed at the same time. And as supporting forms, you have to file I-864, and G-325A for you and your husband. If you are going to do this on your own, please read and follow the instructions to each form carefully. There are supporting documents that must be included, and if you miss them, the process will be delayed. I hope this helps.
