Is there a device which I can plug into the wall and than plug my power cable from my power supply into so that I can get a reading of how many watts and amps my computer is drawing from the wall?

I think I've seen something like this before but not sure what it may be called or where I can purchase it.

Thanks in advance.

That's good! Thanks for the link badge.

Is there a way I can calculate the amount of power (in Watts) that a component is using simply by knowing the amount of volts it requires?
(P = V x I).

The easiest way to do that would be to use a DC clamp ammeter. This, along with a unit like the kill a watt, allow you to see total and component power consumption. It's what I use.

P = V x A

You need to multiply volts times amps to get the total wattage.

The volts is usually the first thing mentioned on a label on a device, the amp rating is sometimes missing.

You could just use what joefriday said to get the actual reading.
