Here are the answers to some of your queries:
1) The salary offered to your husband along with the accommodation should allow you to manage through. Accommodation in Doha is costly and you may be able to find one around QR 5000 per month.
2) The spouses' name does not appear on Qatar IDs.
3) I believe there should not be a problem if you live together as long as you have a legal, certified marriage certificate but I suggest you have your husband check on this from your country's embassy after he arrives here.
