There are a few possibilities here. The first question is about the cooling fan.
It is normal for the cooling fan to come on after the car has warmed up, and the car isn't moving. The purpose of the cooling fan is to replace the airflow you get when the car is moving. So if you drive down to the store, and come home and sit in the driveway, the cooling fan will come on. If you were driving at slow speed on the way to the driveway, it may be on when you get there.
Do this simple test. Turn the AC OFF (ECON mode). This keeps the AC from turning on the fan. The cooling fan should be off with a cold car. Drive the car around the block a few times to get it up to temp. Pull into the driveway and sit, engine running. Is the cooling fan on? OK, so far, so good. Does the cooling fan turn off?
If the cooling fan comes on when you start the car (and in ECON mode), and when sitting in the driveway doesn't cycle off even after running for three or four minutes, then the cooling fan is running too much. The problem could be a bad EDU, or a stuck relay. Probably not the relay because if it were stuck, the fan would run even with the car off.
If the cooling fan is off when you start the car, and it cycles on and off in your driveway, then the sensor and relays are probably fine. If the temp gauge isn't working, it could be the gauge or the EDU. I'd put my money on a bad connection to the gauge. As a start, a firm wallop to the top of the dash (percussive maintenance) would be a good start. The worst case is to go in and start checking the gauge and EDU. Not pretty.
You say you're getting heat in the car - how cold is it outside? If on a 30 degree day, after you've driven the car for 10 minutes or so, you should be able to turn the heat to HI and feel lots of heat. Remember, it's easy to get hot air if it is 55 degrees outside. If you're getting lots of heat when it's cold out, the thermostat is probably fine.
If you do end up replacing the thermostat, I like going with the 82 degree unit if you live where it gets hot in the summer. If it gets really cold in the winter (regularly below 0), stick with the 89 to make sure you get plenty of heat. Not a big difference, and there is no really bad decision.
