Okay, this is what I like to do. First, I have backed off of the speed benching. It tends to aggrevate my tendonitis. I hit an ME upper body day every four days with every 4th or 5th workout as a DE day.
Typical ME day:
ME Exercise: 2-4 Board Presses
Reverse Band Presses
Incline Presses/Decline Presses
Floor Presses
Flat Dumbbell (for reps)
Tricep Exercise: 5-6 Board Presses
Dumbbell Extensions
Barbell Extesions
JM Presses
Tate Presses
Shoulder Exercises: Seated Dumbbell Cleans
Rotator Work w/ Bands
Dumbbell Laterals
Reverse Pec Deck
Back Exercises: Barbell Rows
Dumbbell Rows
Machine Rows
Pulldowns(many variations)
Face-Pulls
Shrugs
Additional Exercises: Tricep Pushdowns
Dumbbell Curls
Barbell Curls
Hammer Curls
Reverse Curls
Grip Work
These are just a few examples and you can always mix it up with the use of barbells vs. dumbbells, bands, chains, etc... As far as your board specific questions, I believe that 2-4 boards should be used as ME exercises and 5-6 boards should be used as tricep specific exercises. Sometimes, we will start with 2-3 boards for the ME exercise and then add a couple more boards to hit the tricep exercise, all in the same workout. Hope this helps!
