Oh man, that sounds like a tall order to increase your bench and deadlift by 65 and 100 lbs in roughly 1 month. The squat doesn't seem as monumental as your goal is only 30 lbs away.
My current maxes are 315 for the bench, 405 dead/430 trap bar, and 315 front squat (haven't done any serious back squatting for awhile).
I've never really stepped back to think hard about how long it took me to progress, and what I did, but I will now and offer up some advice.
I started up lifting seriously again (after a long break from an injury) about a year ago. If I recall correctly, by bench max was ~240-250, deadlift was ~345 (10 months ago), and front squat (I'll use that since it's my recent squat) was about 255-265 (8 months ago).
So just to keep the numbers straight, bench: +65-75 lbs in 1 year, squat: +50-60 lbs in 8 months, and deadlift: +60 lbs (80 lbs for trap) in 10 months.
The easiest by far of the three for me to increase was the bench, so that's where I'll start. What worked very well for me (and is still working) is mixing high volume/lower weight one day of the week, while doing high weight/low volume the other bench day of the week. On Tuesdays I usually pick weights that I can do several sets of 10-12 with. These sets will NOT be easy, so don't go too light. You should be in a place where if you attempted another rep after your 10th - 12th (depending on the goal), you most definitely hit failure. Then for the heavy days, go warmup set, then working sets of 5 and 3 until you start maxing out on singles. I'd usually hit failure every time on the last set. They say you shouldn't test maxes every week, but it's worked just fine for me. After you hit that last heavy single, back off to the weight that you did your first working set for, and rep it out as many times as possible. So yeah that's what's been working for me on the bench.
I'll go deadlift next because it was harder to increase than bench, but easier than the squat. I would mix it up from week to week with different variations of the deadlift. One week would be conventional, the next would be trap bar, and the next would be rack pulls from just below the knee (that's when you can really pile on the weight). I would also do explosive deficit pulls from a pretty high platform with a back off weight at the end of my pulling sessions. That's been working for me pretty well, but I've had stalls.
The front squat has been monumentally hard for me to increase compared to the other two, and so fittingly I have the least advice for increasing your squat. I'll say go through your heavier sets, and then instead of stopping after your last set, back off to the weight you did for your first working set, and do explosive intense sets of 3-5, and do a lot of sets of those. If you choose 3 rep sets, do 5-6 sets. For 5 reppers, go 3-4 sets.
Hope that helps a little, and someone will probably tell you that in order to drastically improve your lifts that much in one month, you'd need some juice, Capri-Sun of course lol
