Sometimes there are two temp sensors, one for the gauge inside and one for the engine management. You have possibly replaced the wrong one. Have a look to see if there is another, if so disconnect one and see if gauge drops in car. if it does its the other that needs replaced.

Sounds like the ISV (idle stabilizer valve) is screwy...Take it off, spray some carb cleaner in it..refit it, if it doesn't work replace it.

Sounds like a thermostat sticking. Some things to do. First check coolant level is up and moving. Second (most likely), change thermostat. Very easy fix for backyard mechanic. Make sure to put thermostat in so water flow is correct direction. Look for arrow on side of thermostat. Next, is belt to water pump loose. Another easy fix in most cars.
