Default 85 overheating problem

It all started when I replaced the radiator with a new one, but then the new radiator was leaking even more than they old one. I removed the new leaking radiator and left my coolant hoses open and exposed to the air for a few days or a week while I returned the leaking one for another. I put everything back together and thankfully fixed the leak, but had opened a pandora's box of new problems. I noticed the coolant temperature now skyrockets up and the front cooling fan turns on when the key is in the "on" position and continues when the engine is started. I'm assuming the front cooling fan is a whole problem of its own and possibly just a short or the relay. I believe the overheating may be caused by the thermostat drying out and becoming faulty? Maybe the thermostat and coolant temperature sensor? Before I noticed the overheating I drove around the block and hear a slight squeaking noise from the engine only during acceleration and I think the water pump could be faulty or just trying to hard to push coolant through the stuck thermostat. Maybe I'm wrong or right I just need someone to give me the motivation to get up and fix this thing again it's been sitting for a year and it's to pull her out from the grave. Any advice, ideas, anything would be much appreciated.
