Welcome to the forums.
The fuse should be the first thing you should look at for the fuel gauge malfunction. If your 92 is similar to most later models, there is a fuse panel in the engine bay and another in the trunk. I am not exactly sure in which panel the fuel gauge fuse is located. If you still have your owner's manual, it should tell you in there. Do you know how to tell a blown fuse from a good one?
About the airbag message, check for codes and post them back here. To get codes, start the engine (technically, you only need the ignition on, but you have a better chance of capturing current codes with the engine running), press and hold the A/C OFF button and the WARMER (red) button at the same time until your display lights up. Any codes stored will start showing up in the display beneath your speedometer. Copy these codes down. Testing is done when "PCM?" is displayed. To get out of the system press AUTO or just turn the engine off.
