I'll always help because you have a great attitude.
OK, for starters back thickness exercises are not rest/paused for safety, forearms and calves are also not rest/paused. Back thickness is usually 2 straight sets, 6-9 reps for the first and 10-12 for the second.
Now, for a rest/pause set, lets use incline barbell bench press. You do as many warm-ups as needed to get mentally and physically ready for the rest/pause sets. You are using a rest/pause number between 11-15 reps, meaning the total of your 3 sets combined should fall in that range (7+3+2 for example). You pick a weight that you can get 8 reps with say 275 (just a random weight), and start. You do the first set and get 9 reps, you rack the weight and take 15 deep breaths, about 20-22 seconds. You unrack the weight and get 4 reps, rack the weight and get those 15 deep breaths again, unrack the weight and get 2 reps and you are done except for your stretching. So for your rest/pause set you got 9, 4 and 2 reps for a total 15 reps. You are gonna go up in weight next time because you were at the top of the rep range, say you go to 280. That is how rest/pause sets look. Only rest/pause those exercises that are supposed to be.
