2. Satisfaction is often measured using a questionnaire. See the examples in the definition of questionnaire.
3. The difference between satisfaction and user experience is that satisfaction results from use, while user experience results from discovering, adopting and using the interactive system, through to final use and recollections of use. In addition, user experience can be influenced by more than just use, for example brand image, price and opinion of others, but it is still related to actual or imagined use.
