yes

Yes, just tell the creator waht happened and ask them to ask for a reroll.

You might want to add them and do it over chat to make sure they know, but if you also write it as a comment on the giveaway page then it will help the process along. The creator would then be able to point to your comment when contacting Steamgifts as proof that you want the giveaway rerolled/proof that you already own it.
