I'm not sure that bench presses do anything for your lats. Pullups, pulldowns target the lats.

Also, LEN, SFTS does have a point - it may be a good idea not to just work the biceps and completely ignore the triceps. Huge imbalances in muscles may lead to injuries in the long run. Also, if you're only in it for the show, I think a nicely sculpted triceps is worth more than a huge biceps. ;) You may also want to work the deltoids (shoulder) a little bit.
