Solution:

Edward is Bella's date.

As no two of them have the same number of preferred traits - from (1), exactly one of them has none of the preferred traits and exactly one of them has all the preferred traits.

From (4) and (5), there are only two possibilities:
* Lautner & Edward both are tall and Jacob & Welch both are fair.
* Lautner & Edward both are short and Jacob & Welch both are dark.

But from (2), second possibility is impossible. So the first one is the correct possibility i.e. Lautner & Edward both are tall and Jacob & Welch both are fair.

Then from (3), Jacob is short and handsome.

Also, from (1) and (2), Lautner is tall and fair. Also, Welch is the person without any preferred traits. Edward is Dark. Lautner and Edward are handsome. Thus, following are the individual preferred traits:

Edward - Tall, Dark and Handsome
Lautner - Tall and Handsome
Jacob - Handsome
Welch - None :-(

Hence, Edward is Bella's date.
