As you are not a British or EU Citizen, you need to go through the non EU/British line. This won't change.
They may take your fingerprints, they may not...depends on if they're doing that process in Birmingham yet.
Just have your passport open to your visa page with your landing card & hand it to the Immigration Officer. They may ask you general questions to make sure that you received your visa through the proper channels & they may ask where your husband is.
It's not a big deal, just relax & enjoy.
