These types of posts always confuse me. If you have good training partners why not go to them for advice? I'm hoping you are just looking for other viewpoints to compare to your training partners advice.
The most important part of a meet cycle is "peaking" being in the being fully recovered muscularly and CNSly without being over-recovered/relaxed. While the first weeks of a cycle vary significantly between people, everyone I have trained with has done pretty much the same thing in the last three weeks.
3 weeks out - Heavy: at least a second attempt but less than a third
2 weeks out - Openers: self-explanatory
Meet week - 1-2 days in the gym, no work above 50% maybe a couple sets of five
Depending on how you train e.g. linear periodization, westside, sheiko, etc., the weeks preceding can be very different. If you just want tips I can throw out random shit.
Shirt work with boards can be give your CNS a kick in the ass and get you used to heavy weights that you should be handling in a shirt, however make sure you get enough full-range work. Being new to gear you need to be able to touch without fucking up your form, boards will not get you comfortable with this.
I would advise against adding in too many squat variations close to a meet. You want to be as technically proficient as possible to get as much your best total in the meet. If you haven't done a free squat with a straight bar in several weeks, your technique will not be perfect.
Personally I would advise against trying to add 10 pounds for this meet. Just get the gear tailored if you want it tighter.
