I see ...
If you want to do 5/3/1, I think you're going to need to purchase the book and read it (or get a proper explanation about what it is). It focuses on 4 major lifts. Those being overhead press, deadlift, bench press and squat. In a single workout you do one of those exercises using the 5/3/1 rep scheme. Then the rest of the workout would be accessory work. By only doing bench press and squat, both of which using the 5/3/1 scheme in the same day, you're going to run into problems.
An option is to do 5/3/1 as intended in the book, but only do two of the workouts per week. So week one do press on Tuesday & deadlift on Friday. Week two do bench press on Tuesday & squat of Friday. That way you can still do the accessory work and build the movements/muscles that are lacking. Jim Wendler even mentions doing it twice a week in the book. Your lifts may not increase as quickly this way, however it will still work.
I don't recommend doing only bench press and squat in your workout. To get stronger overall, you're going to need a lot more balanced workout plan.
