Damage to speakers, either from overpowering them or under-powering them, usually isn't something that sneaks up on you. Back off the volume if things start to sound bad and you should be fine. You are almost always better off with too much power than not enough. Clean power (even too much) isn't as hard on a speaker as clipping (from not enough power) is. I power my floorstanders with amps capable of 700wpc each and there are no issues.
As far as what other potential speakers you could get that might put that power to use, well that is a very open-ended question that depends more on your preferences than anything else. And honestly, 185wpc really isn't that much power.
