New to boxing help

I am new to boxing not to WOW been playing for 3 years. I have 3 accounts and 4 70's but I just need some help to set up a system to dual box a 61 mage and a 70 Shaman Healer to run with him to heal him so I can level faster. Is there a way to control 2 computers with one keyboard and mouse at the same time or what should I do. I also want to start a new pair of Shaman. Any advice would be great. I have a basic desktop that can run WOW at 50 FPS maxed graphic setting and a Laptop that only does 20 FPS on min setting (on a good day)

Thank you for you help
