Belowclouds,
its not difficult for the wife to get the residence permit. In order to get it, she needs to come here to complete the required procedures and once she got it, she can travel to and from Qatar without any restrictions, as long as the RP is valid.
TAF Oscar,
we do have a liquor shop, where you can purchase all the available alcohol products, but you need a licence, which costs you from 500 to 1000 QR. It’s a refundable deposit.
Cheers.
