canon ftql is one of the great cameras. does the meter work? Make sure it has a battery, read through the manual linked above, find some basic books on photography at the library and wander through those so you can get a feel for how high and low speeds and wide or narrow lens openings work together.

Then put a roll of film in it and screw up -- i guarantee this, but if you pay attention to what you're doing at the time you will figure it out by the 3rd roll and you're on you way.
