There is nothing that says you can't contact the boss yourself to find out a little more about the job and what/who they are looking for. That would perhaps show more initiative than getting OH to do it for you. It might also make them realise you have some get up and go. I have always done this before an interview and so far it has never done me any harm. You could always ring and ask for either a phone appointment at a later stage or for a face to face appt. All you have to say is that you are interested in applying but wanted to ascertain beforehand what they are offering and what attributes you need to have. It's all research and preparation isn't it?
As for working together, when we first together we worked together and people didn't know. We eventually got married and still people hadn't realised. Very professional!!
