I know on previous phone's I could select a "category" or "group" and all of my contacts would be sent the message. Is there some type of functionality for that on the storm, or is that something that I would need to submit a "feature request" email for?
I don't think you can. On the BB the only way I saw to send SMS to more than one person without adding each one was with groups. Groups is not the same thing as category though.
when they recieve it, does it look like a MMS message, when all of the numbers you sent it to show up? Or does it show up like it was only for that person?
