Need some w/o advice to balance physique!

Hello guys, I'm currently very focused on acheiving my goals, which are to get stronger and being consitent w/ my diet and training, and balancing out my physique. I'm in great need of balancing my physique due to my narrow shoulder width and humongous legs. I was thinking about training chest a lot harder since my bench hasn't gone up in about 2 years lifitng light weight for my size. I could dead 225 for 5 and squat 205 for 5, but can only bench 165 for 5 at best. I would like some advice on upping my strength in all those lifts. Thanks in advance.
