If you want to add some refrigerant, get a kit with a pressure guage. The fittings are sized so that you can't get low side stuff to connect to the high pressure side. Its a safely or idiot proofing thing.
You want to see around 32-33 PSI on a hot day (80F or more), doors open, fan on high, max cooling. If you add too much gas, the evaporator temperatures will not be cold enough to get proper cooling and dehumidification. If too low, the evaporator will be too cold and will ice up.
If too much gas has leaked out, then you need to add some gas to activate a pressure switch before the compressor clutch will activate.
