Replying to Crop Sensor vs. Full Frame and lens focal lengths

I was wondering if someone could give me a link so I could get a better explanation of the differences between a crop sensor and a full frame sensor with regards to lenses and the actual focal lengths you get from a lens on each?  For example,  I have a D7000 with a 16-85, a 70-300, and a 50 1.8.  I'd like to cover a similar range with lenses for a full frame camera.  Would a 16mm prime on a full frame camera be similar to a 16mm lens on a crop sensor?  I know a FF has a wider field of view but couldn't find any great explanations by searching around.  I also had a second question.  Are most primes created for FF or crop sensors?  For example, when I put my 50mm prime on a full frame camera am I actually seeing the correct FOV of a 50mm lens?  I'd like to learn more myself so if you have a link I'm more than capable of reading about the subject.
