I would say no to the rooster... unless you want eye-candy. This is your hobby, do it the way you want. I live on a ranch, we have every chicken predator...well coyotes, coons, weasels, owls and hawks. I do have great vegetation, and cover for them, but I don't let them out everyday. Having a good mature rooster does help my flock, not all roosters are good.
Personally, I have found that people tend to have more trouble raising up a rooster with flock mates. The rooster grows faster, and becomes sexually mature before the pullets, and without older birds to thump some manners into him, he often becomes a bully.
If you want a rooster, wait, raise up your girls until they are laying, and then look around, people always have perfectly beautiful roosters to cull. You want one that has been raised in a multi-generational flock, perhaps with a head rooster that is a year old. One that has not been culled cause he is just so darn nice, but an extra one all the same.
