Bad color on two Samsung Syncmaster B2330H

I have two Samsung Syncmaster B2330H's and an NVIDIA GeForce GT 420 graphics card. I am just converting from film cameras to digital cameras and digital processing thru Lightroom and CS5. I do not have any experience dealing with making sure the color on my screens will be close to what returns from the print labs. I am afraid that the color in my photos my be badly off. The screens look a bit green and I can't seem to get rid of it. I have read that there may be a color balance issue with these monitors. I have played around with the NVIDIA control panel, the display calibration controls(it say it uses a wide gamut color profile...not helpful) and even adjusted the gamma levels with "Quick Gamma." Should I be messing with the WCS and ICC Profiles? How can I test the color balance? I don't want to edit photos only to find out that the edits way off and have the prints return from the lab "off color" and then have to try to adjust color balance on the monitors to match the labs. I can't even set the color temperature! Somebody help me!
