Bad wheel bearing on 95gt?

My 95 gt has started making rattling / clicking noises while driving at certain speeds. I suspect it is the front pasenger wheel bearing but I'm not 100% sure.
The noise changes with the speed of the car - it is at its worst right around 45mph (really convenient since thats the speed limit of the road I live on). Higher speeds the noise goes away some and at lower speeds it also goes away. Not really noticeable at speeds less than 30mph.
The other interesting thing is the noise goes away completely when turning right. At any speed.
I suspect I have either a wheel bearing or a brake rotor problem but I'm not sure which. Any input would be appreciated. I haven't had time to take the wheel off yet, I figure I could take off the wheel and turn the rotor by hand with the caliper off to see then if its bearing or rotor.
Or am I barking up the wrong tree? The fact that the noise goes away completely when turning right is what is puzzling me. Even very slight right turns will silence it. To make life even more interesting I also have a different rattling noise coming from under the dash that I will also tear into soon.
