Those pressures are ok, depending on what your ambient is and engine rpm. I don't know if you did it but a person should always spin the compressor over by hand MANY rev's once the system is assembled.

The noises that you describe can be due to unstable/loose mounting and/or loose drive belt. Check this first and then check your pressures again with engine at 2000-2500 rpm, high fan, max a/c, and the condensor fan running. Also, let us know the ambient air temp where the car is.
