I checked the clutch reservoir and it was empty. I put some new Dot 3 brake fluid in it and started it up and it helped some. The clutch pedal sprung back and didn't really stick. Not 100% though. Am I naive to think that this alone will do the trick?

When you say change the master cylinder, are you talking about the one for the brake as well or just the clutch??
