Ah, I see.
Well then, carry on doing your oats and whey post-workout. I'd say the peanut butter is better than "cheese spread," so you can eat that plain a couple tablespoons a day and/or toss it into your PWO also. Try to avoid the oats until after you've trained for the day. Based on your height/weight I'd say you're at a pretty good raw weight and your bf% is pretty enviable too, so unless you're cutting to ration your good stuff I'm not sure it's all that necessary.
You could try switching up your routine a little if you find you're plateauing. I'm doing a upper-lower split four days/week right now that sees two days upper body and two days lower body; one day of each is max effort (lifting heavy) and one day of each is dynamic effort (lifting fast). I try to get in some intervals or a long walk/jog on each of those days too. There's a lot of flexibility in the program and it's still built around the Big 3 lifts. Just a thought.
Oh yeah, Godspeed.
1) eat real food - more vegetables, moderate meat, moderate fruits, less grains, less sugar, less vegetable oils.
2) exercise - moderate intensity cardio, sprinting, heavy lifting, dedicated stretching and mobility.
3) live - relax, de-stress, meditate.
