Its leaking coolant but not from the radiator or hoses.
There is little weep hole under your water pump and coolant will leak out of it once it needs to be replaced. Your water pump will sometimes make an awful high pitched squeal without leaking which in that case would also require replacing. I'd also suggest checking heater hoses because they can also leak.

What may assist in your diagnostic is a system pressure tester.This has a hand pump to where you can pressure up the system to 12 to 17 lbs and this really helps bring on hard to find leaks. You may be overlooking coolant leaking from the "weep hole" in the bottom of the water pump or a place that might become much more obvious inspecting this system under pressure. The tester also helps diagnostic by noticing if the system holds pressure for a sustained amount of time.A small leak will drop your 12 psi in a matter of a few minutes and you will continually need to pump a few more times to keep that pressure which further indicates the system is leaking down.

Inside the coolant reserve tank there is a sensor for coolant level.
Over time,this sensor can get stick.
Inspect the coolant reserve tank for crack or leak.
Locate the coolant level switch/sensor and soak it in clean warm water.
Make sure it's free to move up and down the float path.
Top off the coolant tank with coolant only.

If you cant see any water coming out anywhere then the only choice is a blown head gasket.
The reason the resorvior had a leak was the pressure from the engine got into the coolant and blew up the reservior bottle. This is a real common problem with saturns.
Get the car inspected. A simple test a a reapir shop will confirm this.
Be sure to flush all the stop leak out or it will clog the heater core up and the heater will not work.

i would remove thermostat first to see what happens ,if it still over heats is your warer pump

No, these problems are not related. The radiator is a sealed system and you may have a leaking hose, bad water pump or the radiator may have developed another hole in it.
The A.C problem is one of three things.
1. The A/C Freon has run out of the lines. This is a fluid used to maintain cold temperatures and produce the cold that actually comes out from your vents. It could be as easy as recharging the A/C system.
2. It could be the high pressure line that feeds the freon to the system. This would require replacing the hose and recharging the system.
3. It could be the A/C Compressor is bad and need to be replaced and the system recharged.
Each of these are progressively more expensive and should be fairly easily diagnosed, albeit by a automotive professional. I would not suggest you try to fix this yourself.
