With your stats and numbers I would stick to basics big time. It's not your bench that's weak bro, its your deads and squats if you want to add muscle. If I was you or if I was training you I would have you train 3Xs a week. A squat day, day off, a bench day, day off a dead day, couple days off. Mon, wed, Fri or tues, thurs, sat.... One week the squat day would be higher reps and dead day would be building up to a .max 2-4 rep set and the next week I would switch. I would include a cpl assistance exs. On squat day higher rep stiff deads or flute ham raises and calf and ab work, bench day would be mill presses, strict laterals and dips and dead day would be pull downs or ups(depending if you can do .pull ups), rows(cable, BB or hammer low rows) and oblique work.
I would not over think it. Uses the exs that are comfortable (example, if db mill presses are more comfortable than BB just do DBs, if Rv grip pulldowns or parallel grip pulldowns or whatever kind feel best do them for your pull downs).
When you are using 4+ for reps on deads and squats you will look like a diff man.
Don't over complicate it and enjoy your W.O.'s ... If you feel stale and want an active rest just do whatever you feel like in the gym for a cpl weeks then return to the basics.
If you follow the basics, don't over think it, get enough (but not too much) food and get your rest you will make huge progress in the next 6-12 months.
One last thing though. Record yourself doing deads and squats from the side and review from time to time. Keep your form perfect. If you have a good trainer there or a competative power lifter ask them to watch your dead and squat tech from time to time.
Good luck.
