What adjustments do I need to make to get my printer (Xerox Phaser 8200) to print the true colors that I see on the photoshop screen? WHen I print now using the standard settings they aren't even close.

The question is: what adjustments do you need to make to get Photoshop to show you what your printer will print?
As Richard says, you should see if you can get a color profile for your device (printer). You can use that to create a Custom Proof setting (View>Proof Setup>Custom...)
In this dialog, make sure that your Rendering Intent is set to Absolute Colorimetric (this is a preview of what your image will look like after it is printed, not the final image rendered for the printer). In addition, the paper you use in the printer will have an effect on the color output, so you could check 'Simulate Paper Color' at this stage.
When printing you should use either Perceptual or Relative Colorimetric as your rendering intent. For more information here's an article:
