Dragon's Dogma: Dark Arisen Confusion

Hello everyone. I got Dragon's Dogma at launch and like it a lot. Since we cannot add Dark Arisen to the normal game, I have some questions.

If I buy a retail Dark Arisen, do I still need my normal game to play? I am wondering if I should sell the game now before it looses its worth.

My second question is how the rewards for Dragon's Dogma works. Does it read if there is save data on the Xbox hard drive, or do I need the disk?

My last question is a lot like the last one, will all of my saves from the original game be moved to Dark Arisen without the disk?

Thanks for the responses, everyone.

It's an expansion pack that also includes the original game. So it's really the finished product the game should have been, resold as an expansion pack.  It should recognize your saved data no problem.
