If I were you, I'd avoid Fridays as they do sell out. They are more crowded then weekdays. Go the 6th or 8th or the 13th or 15th.
The tickets went on sale really early last year, May 1. Just keep checking here on the DIS in the Theme Parks board and you'll know when they go on sale!
Have fun planning!
