What to bring on safari?

I'm planning on going to Zambia in a few years, and I will be bringing my Nikon SLR as well as my Canon SLR and a few lenses. So my question is what would be some camera bags that you would recommend? I need a bag that can carry what I've posted above as well as a lap top. A way to carry a tripod would be a plus but is not a huge requirement. While I'm at it too I know I'll need some sort of jacket when it cools off so what would you guys recommend? The company I was looking at doing it through recommends clothing that will blend in with the landscape.

Go to the source of it all - B&H cameras. http://www.bhphotovideo.com/...4075788797 It's mind boggling if you have a chance to visit the store in New York.
