You now have 3 different speakers making up your system. The 201s which are garbage, the c's which are quality entry-level, and the mini which is quality/specialty. When you mix it all together, you're just going to have a home theatre disaster. If you haven't purchased some of these yet or can take some back, stop and do some thinking about what you want. With those speakers, I'd try to minimize the mismatching by putting the Energy's up front and the BOSE in back, but that's a small help to a much larger problem.
1 watt per channel is plenty of power. You'll never use 10 continuous watts in your life... ever. Wattage is something that makes people think they're getting something special but in reality, they're incapable of using it without going deaf. It's a sales gimmick for unschooled consumer-victims.
