Extra Data fields in video upload and user profiles

Hello

I am a very new user of vshare. The vshare script seems to preform all the functions i need, apart from the ability to add extra data fields to pages.
For example I was wanting my users to have the ability to enter the country then state then city of where the video was taken. So after they have uploaded the video other users could then search for the videos via location. I would also like to use the same concept with user profiles but with different data.
Would any be kind enough to give me some direction on how to do this?
Thanks
Dan
