Remove and clean the flush valve and the flush valve seat(it is the flap that opens up to allow water to flush the toilet). Once the edges of the valve and the seat are cleaned, possibly with "0000" grit bulldog steel wool, it should not leak anymore. To make sure it is not leaking, once tank has refilled completely, put some food die in the tank. If, after 10-15 minutes, the water in the toilet bowl is colored, you have a leak from the flush valve. Replacing the flush valve is very easy - just bring the old one with you to the hardware/plumbing store and ask for a replacement. Blessings and good luck!!

The level is determined by a floating device connected to the water valve. Some are on an angled arm and some move up and down. Determine how your valve is shut off and either change the big round float or adjust the clips on the rising one. Just keep the level below the overflow and the flush handle to avoid a running toilet or a leak.
