If bandwidth isn't an issue then each miner can have its own work and directly mine to a pool, it's not like you are going to set them manually, free tools are available, you just set the IP range and it will fill in the pool worker details for you.
If you want to save on bandwidth, you will need to use a mining prox or a few of them, a mining proxy basically connects all your miners in one big miner/worker, it's like having one control board connected to a few hundred/thousands of hash boards, the pool will "think" you have one super mining gear.
There is yet to be a made a simple newbie-guide on how to set up a mining proxy, it's a bit complicated.
