The project was for my wife's '98 CE, and it was easier than I thought it would be. Lasted no more than 20 minutes tops 
The objective was to replace the burnt out 194 bulb that provides the backlighting for the right part of the speedometer. Here are the steps:
1) Locate and remove the 2 Philips screws (circled in yellow) on top of the gauge cluster plastic frame.
2) Pull the frame out grasping the top and bottom ends (you may need to use a screwdriver to gently pop out the sides). Don't worry about the plastic material of the frame; it's fairly strong.
3) The instrument cluster should now look like in the pic below. Next, locate and remove 3 Philips screws (circled in yellow) from the actual cluster.
4) Lift the cluster up and out of the dashboard, and unclip the 4 electrical connectors from the cluster.
5) To access the backlighting bulbs, locate the 3 green-colored sockets (circled in yellow) on the back side of the cluster. Just twist to unlock, and pull out the 194 bulb attached to the socket. It's that easy
The pic below shows the burnt out bulb on the far left, what the actual bulb looks like in the middle (with the green rubber cap), and a brand new 194LL clear bulb ($2.75 for a 2-pack from Wal-mart). The green rubber cap must be saved for the new bulbs since that is how the green colored backlighting is obtained. Of course you can put in a different color rubber cap (like blue or red) but my wife loves the stock green. You can find these rubber caps at your local auto parts or performance shop, or find a local dealer at http://www.autometer.com.
Hope this helps anyone out there with backlighting problems or issues
