Possible AC compressor replacement in 98 Civic?

Hey there. First post. I'm hoping to get a little help on a 98 Civic I just purchased from a classmate. I live in Houston, Tx where it's currently 95 degrees F with 60% humidity... needless to say, I'm dying without AC! When I purchased the car, my classmate said everything works great, but a mechanic told her that it needs a new AC compressor. I also have a 99 Civic that I've done plenty of work on so I thought, "heck, I could probably tackle this issue!" But in reality, I have no experience with AC systems. So I hooked up an AC gauge and recorded all of the readings in the shade, per the Honda service manual. I also recorded the readings on my 99 Civic just for comparison. Here are the readings:

98 Civic
- Temp: 60 degrees F
- High pressure: 205
- Low pressure: 34

99 Civic
- Temp: 45 degrees F
- High pressure: 200
- Low pressure: 27

Do these readings indicate anything in particular? I'm having a difficult time wrapping my head around the Honda AC charts, but if I understand correctly, the 99 Civic may soon need a little extra R134a, but I don't know what the readings from the 98 Civic could mean. I will say that the air coming from the vent in the 98 Civic seems a little humid and has an interesting smell... possibly a leak? Any advice would be extremely helpful... thanks!
