Just because the Onkyo has a higher maximum wattage rating than what you're using now doesn't mean it's going to be sending more power to the speakers. It's directly tied into how loud you have the system. Were you happy with the volume levels you were getting already? If so, then the Onkyo should be able to deliver the same amount of power but it would likely be cleaner power and actually better for the speakers. If you weren't happy before and you're looking to go even louder than you were going before, then you'd be using more power.
How big is the room you're trying to fill / how far away are you from the speakers? Unless you're filling a very large room I think you should be able to hit the comfortable upper volume level limit before you're in danger of giving the speakers too much power. You probably don't have an SPL meter to tell us how loud you like to listen to them, eh?
You can certainly get new speakers if you want to, but unless you're going to be pushing the speakers significantly harder than you were already, there shouldn't be any issue using amplification that's able to output more than the speakers are rated to handle.
