it's your battery! simply jump it off of another car for a quick assessment. starter clicking is a sign of not enough amperage, and not a failing starter. Assuming you tested the battery off of a home charger system, you most likely have a trickle charger or some sort. They are not capable of charging a dead battery and will just prematurely say that it's done charging. 99% sure it's the battery.
The best thing to do after starting it is to remove the battery and get it charged/tested at your local auto parts store for free. then report back
as for the leaking, it's b/c your drains are plugged and now it's overflowing ...
