How do I remove all of that? I'd rather people focus on the posts and not all of that other stuff.

Go to Administration Panel -> Users and Groups -> Users -> Profiles -> Find the row(s) that has the field(s) you want to remove in post, then click the button on the far right.
Once you click the edit button, find the "Display :" field and unceck [] Messages.
