Answer 1

You're not supposed to, but they don't have names on them, unless they're signed.

I'd definitely sign them.

Answer 2

Technically they are NOT transferable.  However, unless they are signed there is really no way for Disney to know that they were given to you.

You can not go to the same park on both of the days.  So if they went to Disneyland you MUST use them at California Adventure, and visa versa.  Also, you have 30 days from the date of first use to use the 2nd day.  So if they used the first day more than 30 days ago the tickets are now void.
