Your goals are to squat, bench and deadlift a lot. Getups and pistol squats will not help you do this, but doing this will help you do getups and pistol squats. Those are in any case technical and require some coaching, considerably more than the basic barbell lifts. So forget about them.
What you need to do is something like,
Firstly, get some microplates (0.25, 0.5, 0.75 and 1kg), and when you go to the gym always use the same barbell (most gyms have gear from different manufacturers and the weight won't be consistent). Then,
A) squat for 3-5 warmup sets, then work weight 5,5,5; press in the same way
B) bench in same way; deadlift in same way, but for one set of 5.
alternate these two workouts doing them 3 times a week, and each time choose a third exercise just for fun and really push yourself on it - chinups, curls, lat pulldowns, dumbbell rows, whatever.
Start with the empty bar for squat, press and bench, and 40kg for deadlift. Add 2kg a time for squat, 2.5kg for deadlift, 1kg for press and 1.5kg for bench. If you miss the target reps, go home and eat a huge steak, try again next time. If you miss 3 times in a row drop the weight back 10% and build back up. Thus in about 6 months you would be squatting around 90-100kg, benching 70-80, pressing 40-50, and deadlifting 120-140.
This will be a good base and you can then build from there. You goals of squatting 1.75xbw, benching 1.5xbw and deadlifting 2xbw, the squat and the deadlift are reasonable for a healthy young guy in 12 months, the bench would be more like working up to 1-1.25xbw in 12 months and then it would take another 12 months to bench 1.5xbw.
