Does tesla needs coolant? what about break fluid?
Yes it has coolant for the battery pack, but it doesn't get hot so it lasts a very long time.
Yes it has brake fluid for the conventional disk brakes.
As I recall here's a little bit of lubricating oil in the gearbox.
It has windshield washer fluid.
AFAIK the only other liquid is in the cupholder...
And the driver
How about recharging the AC?
The roadster air condition uses R134a as refrigerant. Not very green but state of the art in 2008. AC systems constantly leak a little amount of refrigerant, and are checked/topped up during service. Some national laws enforce leak detection if there is an excessive rate of loss.
Model S HVAC system will use a different refrigerant. Franz calls it "environment-friendly". Let's see.
