A/C Problems. Please help

I've vacuumed the system and the vacuum held for over 24 hours. I've converted to 134a. I added the oil charge and the pressure gauge read 60! Then I started to add a can of refrigerant and the pressure went to 110! The compressor kicks on when I hit the a/c switch on the dash.
What did I do wrong?
Is the low pressure valve the one towards the top of the compressor?
Could my expansion valve be stuck?
With the pressure reading in the 90's should I evacuate some of the refrigerant and oil?
Please help as it is getting hotter than ever in H town.
