Thanks for the comments guys.

It looks like I need to find out a little more about the visa situation - I think the company can apply for one for her, but I want to make sure she isnt too bored at home all day doing nothing without a job :)

Do you know off hand if my wife wasnt to get a full time visa and just came for visits, what the longest time she could stay for. Is it possible to get a 3 month or longer visa for visiting?

On the expenses side, I guess 2000 a month for food shopping is reasonable, and as the accommodation and car are paid for we shouldnt have to many other expenses - apart from eating out or doing other leisure activities.

Would 5000 Riyals a month be enough to cover everything (food, leisure) for a modest couple?
