Taking a break from work for a couple of minutes. I looked through my factory manual CD (yes, I do have one in my briefcase), from what you said did and didn't work covers 5 different fuses.
So, here is what I think is happening.
1. Rule out direct shorts to ground since parts of the circuits work.
2. Instrument lights: Replace all of your bulbs and clean the contacts. You will have to remove the instrument panel to do so. I had the same problem with my '02 when I bought it.
3. Cigar lighter: If you check with a multimeter to ground, you should always see 12-14volts. If not, you have a problem upstream. If you do, the problem lies with the cigar lighter or the wire running to ground.
4. Interior light: Another bulb problem probably. A lot of times, the contacts are just dirty. Old bulbs sometime loose their vacuum integrity over time and will not light up in atmosphere. Also check wiring harness if possible.
5. Tach: Check the wiring from the tach to the distributor. Possiblity of a break in the wire or dirty connection. Outside chance of a dead tach.
6. Temperature gauge: This is not unusual. Clean the wire connector on the sensor. You will be surprised at how much oil, dirt, and crud you'll find in the spade connector. I'd put in a new spade connector and then put a extra piece of shrink tubing over it to seal out everything. If you haven't done any maintance work on the cooling system, you may be in the need of a radiator flush (minimum) and/or radiator recore (maximum). If the gauge is bouncing, the grounding of the gauge at the instrument cluster needs to be improved.
I hope this helps.
