Take the reservoir cap off and run the car till normal temp. I think when your coolant light came on and you added more, it put air in the system. This will bleed that air out and vacuum down the system. Make sure the tank is fill enough so air cannot be re-entered into the system.

2) If you do have a leak somewhere thats also possibly putting air back into your system causing the overheating to continue.

3) Squeeze the upper engine hose right in front of the exhaust manifold near the coil packs with the engine on. If thats hard you your water pump is fine.

I didn't feel like reading everything above other than your first post.
