We had the same worries you have, but quickly found that chickens LOVE to forage freely, so letting them out is a great idea. You will enrich their lives quite a bit by letting them out, as your coop and run sizes are close to minimum, from what most folks say.
Now, the great thing about chickens is their "flock mentality". When you have them out, all you have to do is clap your hands or start to round them up and they'll generally all run to each other. Also, once the first bird goes into the run or coop, the others are likely to follow in quick succession.
Nothing to worry about, really...you'll have it down to a science in no time. My wife and I really enjoy letting the girls out and just sitting in some comfy lawn chairs, watching their crazy antics. Perfect time for an adult beverage and quiet conversation.
