leaking gas from overflow kz650 SR

It was built in August of 1978, so I guess it is technically a 1979 model, right?
Anyway here is what I know is wrong with it so far:
Petcock is shot, leaks in all three positions.
Sometimes leaks fuel from the overflows. Sometimes not. I'm not sure on how often. Sometimes I will smell like gas or see gas on the ground, sometimes not.
Might have a slight hesitation from idle to 1/4 throttle, but might be my clutch control.
Has new wires and plugs, but plugs 2 and 3 were slightly fouled, and were wet.
Small backfire pops every now and then at nearly any throttle setting, except perhaps idle.
Might also need valves adjusted, as that I can hear a tapping from the front of the motor when taking off, and at very low speeds.
It appears to have the stock air box and pipes. Does not smoke at all.
It runs well enough that I went cruising for 80 miles this afternoon.
What should I do first, as that money is a bit tight?
Oh, it has one other problem, hideous graphics on the tank!

Would do the following:
Check and adjust valve clearances;
Perform clutch pushrod adjustment;
Assure fuel levels within specs (clear tube test);
Add SeaFoam to fuel in tank (hopefully clean carbs while riding);
Install petcock repair kit;
Assure air filter is clean, clear and unobstructed;
Perform whatever cam chain tensioner adjustment specified in FSM;
Assure correct ignition timing;
Assure advancer is functioning correctly (might need lubing or both cleaning and lubing).
If problems persist, may require carb disassembly and cleaning (especially pilot circuits) and sync.
Good Fortune!

It hasn't leaked from the overflows in a day or so, so maybe that is going to clear up as well. Petcock is of course still trashed, but I am waiting on parts.
