1. Angelina Jolie
2. & 3. Who cares?
No, seriously I reckon it'd have to be tactile mementos from Earth. You could get anything audio/visual streamed from Earth - all your books, music, photos etc. You could remain in contact with family & friends. Take some little things to connect you to your 'previous life'.
Assuming NASA would be providing the scopes & cameras & laptops (

) I'd take:
1. A little jar of opal chips
2. A small gold in quartz specimen
3. Still thinking.....
