With definite drops in boost, it sounds like you are hitting the knock sensor. To confirm, try some octane booster to see if you then get higher boost. Set your timing back a degree, i.e. 14 or 15 btdc versus 16 stock setting. Set base boost to 5.0psi.
Manually apply vacuum/boost(suck/blow) on small vacuum hose that goes through firewall, to make sure you don't have a leak under the dash to gauge and/or pressure transducer.
Re A/C...since your compressor runs, you must have some freon and you should at least get mild cooling. My guess is a bad expansion valve. A good A/C shop can track this down in a few minutes with pressure gauges.
