Speaker wattage ratings are nothing more than a guide for maximum power input. As long as the speaker is rated for more than the receiver can output all will be fine. As for volume you want to look at the speakers sensitivity (also known as efficiency). The higher the number, the more sound (volume) it will produce. I recommend that people with lower powered receivers (you are in this group) look for speakers that have a sensitivity rating of 90db and above, higher being better (more efficient which requires less power to get a higher volume level).

As for powered subwoofers, they have their own power amplifiers so the power they are rated at is actually what they produce.

Did that help?

However I noticed something interesting. When no sound is being outputted, the reciever turns off the sound channels, and if for instance there's a very quick sound that occurs on the computer, it gets dropped because the reciever can't respond fast enough to turn on the channels and play the sound. Is there anywya to disable this? Not really asking specifically for the RC160 (since not too many people probably have one), but do other Onkyo recievers have a feature as described? I wasnt able to find one.
How exactly do you have the computer connected to the receiver? I have not heard of or experienced anything like this and use a receiver with computer for audio in several systems (all Onkyo equipment). More details will help us to troubleshoot this situation.
