I don't know about in adobe, but I know that in final cut you can do a batch import, and then drag them all to the time line at once. Then I normally select the entire time line and change the speed of every clip at once. To do this in final cut, you press Command+J which might be ALT+J in premier. The general rule of thumb for a stop motion is 4 frames per picture, but that depends on how many pictures you are doing per day and how long you want the video. Hope this helps.
