Most collectors prefer to have the stamp in its original position, on envelope or document. This shows the usage of the stamp as it was intended and will have more value than the stamp by itself.
It depends a great deal on the stamp and how old it is. If there is a special cancellation or cachet on the envelope, it is better to keep it on the envelope. The older the stamp the more likely that the envelop will have more value than the plain stamp. It is better to leave the stamps on the envelope because there is a postage mark that goes over the stamp. That will give the stamp more value.

Yes, they can be. While typically a used stamp has less value than a mint stamp, they are valued on the concept of supply and demand. A high value stamp is typically going to be very rare and high priced for the time frame it was used in. Early versions are also going to be more difficult to obtain than others.
It's actually called a "seal" rather than a "stamp". Please see the Related Question for more information.
