Cooling system question.

Hey folks on my way uphill the upper radiator hose slipped off. and the Temp went up to 3/4. I quicky shut down the car. On the highway and let it sit for about 20mins walked to the gas station to see if they sold 50/50 coolant and barrow a screw driver. I let the car cool for about another 30mins. Opened the top and slapped in some coolant just about filled up the radiator. now that everything is hopefully cool. Is it still safe to drive the car without harming the motor? Also I drove the car home. Rolled it down hill. the Rpms stayed about in the 2k rpm range. The temp gauge reads from cold to 1/4 as I had to turn the car and drive about 2 miles. So whats wrong with the temp gauge? Also there is no milky or brown looking stuff in the oil. However the coolant has some gray stuff ( looks like the RTV sealant I lightly used) for the waterpump and thermostat. I hope I didn't blow the motor.
thanks
