Sounds like are you want to install a closet light to an existing branch circuit which has outlets already. This should be OK, but a few things need to checked first:
What does this branch circuit serve (bedrooms, bathroom, living room/den, etc.)? If the branch circuit serves a bathroom or kitchen, you should not add general lighting to it.
What is the rating of the breaker for this circuit, and what gauge of existing wiring serves the circuit? If it's a 20A breaker, it should be 12 AWG. 14 AWG should be used only on a 15A breaker. For your new wiring, you should stick to the same gauge as the rest of the branch.
What type of lighting fixture are you planning to put in the closet? If it is an incandescent fixture, it should be a recessed fixture with an integrated thermal cutoff to keep combustible materials in the closet (especially on the top shelves) from contacting the fixture.
The placement of the switch is your choice (within reason, of course; keep it away from water like sinks/bathtubs). I'd personally place it on the outside of the closet and use a pilot light switch that will indicate when the light inside is on.
