i know from experience that if your brake booster leaks on an fbody, your brakes barely work at all.. but definitely do check it.

Most likely the booster will be ok.
Idle is 900-1200
replaced the iac with used one
then it rised to 2000
used scan 94 95 to reset iac position
after clicking on that button about 5 or more times it has dropped to normal idle and IAC was about 10-14 steps
after restarting the car rpm is about 750-800
but target rpm is 650
IAC is about 20-25
Faulty IAC?

your TPS is at 1%.... why is your TPS at 1%? it wont try to attain your idle target if the TPS is open.
Good question. I'll try eehach to measure tps. Scan 94 95 always shows 1%
One more moment. The only leak i have is on the pic below. And I can do nothing with it. TB shaft.
its normal for it to leak a bit there. it looks like you haven't adjusted your idle screw. make sure your throttle plates are closed as much as possible (just not so much that they jam in the bore). after doing all this, pull your PCM BAT fuse for a bit just to make sure ecm memory is clear.
Now tps is 0. Strange. I did nothing about adjusting that screw. Rmp just raised and thats it. 700. Then 800 in a week. Then 900 and so on
Idle iac is 40 steps. Is it okay?
Idle is 850.
I'll try to install new tps. I dont like how it operates
