What does codes po586 and po582 mean? Whats the problem?

I put the refrigerant guage on Low side and it fluxuates from 5 psi to 60 psi. I can't get a good reading, because the clutch cycles on for 3 to 5 seconds and off for 3 to 5 seconds....Is this part normal? It blows warm air. I tried charging it, and I can see the line sweat, but only warm air comes out.
WHAT CAN IT BE?.....orifice or clutch?

My check engine light and TracOff lights are on. My codes are P1349, P0300, P0301, P0303, and P0305. My car has 122K miles; and I have just replaced all three oxygen sensors. The car drove beautifully for 2-3 miles after I replaced the sensors; then the lights came back on; and the car idles roughly, misses, and lacks power. I have seen answers here which say that the cause(s) could be failed ignition coil(s); failed oil control valve, or failed mass air flow sensor. I would like to know how to test these components, and in what order, to determine the cause of the actual problem. Thanks.
