Very little, actually. You could get a 50 or 75 watt heater and it would probably not raise your electric bill more than 75 cents a month.
Heaters do not run all the time, they are controlled by a thermostat and when the water gets warm enough, it will shut off until the water temp drops below your set point.

3-5 watts /gallon= 50 watt heater. Get it mail order unless you really want to support your local pet store. http://www.drsfostersmith.com is a great site.

Practically none! Slightly more than a light bulb.

Not much at all, and if you're keeping tropical fish, it's a necessity. (depending on where you live, but it keeps the temp from fluctuating too much.)
