Okay, first off if I am coming off as an ass I apologize but for 1.5 years of serious training your lifts are all pathetic (actually they would be pathetic for 6 months). You really need to trim the fat off your exercise selection. You do not need to add biceps curls, triceps extensions, leg curls/extensions, at this point in your training program. Your entire body will improve just by increasing your major lifts. Focus your upper body day around the bench press and overhead presses. Also, for every pressing movement you do, perform a pulling movement also (e.g. bench press followed by bent over rows and barbell overhead press followed by high pull). So your upper body day could look like this:
1a. bench press variation
1b. barbell bent over row
2a. barbell overhead press
2b. pull ups
If you still have anything left in you, you can throw in some curls and triceps extensions.
leg day should consist of bilateral and unilateral versions of squats and deadlifts.
2a. bulgarian split squat
2b. bodyweight deadlift
As for sets and reps, you will probably respond best to staying above 80% of 1RM. Samples of effective rep schemes include 5x5, 3x8, 4x6. Just pick one.
Asfor progression, on your first workout of the week add 5 lbs to the bar. On the second, focus on adding reps to your sets.
