If you know for certain that your chickens will be closed inside the housing each night, you can get by with less run security (such as netting). But if you think realistically that there's a good chance there'll be nights when they're NOT shut inside the housing, then I'd go for sturdy wire.
You're going to have a decent sized run, so you're going to need something taller. Can you imagine crawling through your run to clean it if it's only a few feet tall??? That would be back breaking, and would get old REALLY fast. I know it makes you want to choke to have to spend so much money up front. But you know what? You won't even think about the money two months later. I'd do it right the first time - it'll make your experiences with chickens so much more enjoyable (and easier) for years to come.
