... how do i choose a focal point when doing large groups?
Just use center focus. You can not focus on multiple subjects.

If people are in rows behind each other and you want all faces in focus, you need to read up on how aperture, focal length and distance to subject affect depth of field. It is, but not in depth, described on page 139 of the manual.

You can use a tool like Online Depth of Field Calculator to do calculate the DOF and 'see' the effect.
