Group photos and focus on Canon?

Hi,

I'm new to Canon, I noticed that the camera focuses alot on a specific thing, do you know of a setting where it can focus on the entire frame? .. I have a really hard time in group photos because it focuses the center people and begins to blur the ones on the far sides..and also that it will focus on a soda can in the table in front of the people instead of focusing on the people, haha, its funny.

I've been looking in the manual, but I get confused.

Its a Canon Rebel XSi with the original lens.
