It's not a straight line process. One app does not fit all.
You can transfer contacts and calender if you first sync them with your Gmail account on your PC. They will sych automatically to your Epic.
I don't keep SMSs so I can't suggest anything there. There is probably a way.
As far as I know, there is no way to transfer your tasks unless you get a third-party app that synchs with Outlook. Google or, even easier, check the PPCG wiki to see all the current choices. I just started a new list.
Videos and mp3s are easy. Just drag and drop them to your microSD. I keep all my music files in a folder called Music. Videos are in a folder called My Videos in My Documents. They play MUCH better on my Epic.

All of this was probably asked and answered before. But WTH!
