It's a lot easier to do this with another person, so grab a friend before you start. Before you advance the timing on an Integra you need to first put a jumper in the passenger side socket or you'll get an inaccurate reading. To get to the socket, remove the kick panel under the passenger side dash (there should be two tabs holding it on). Then reach up and grab pull out the big green socket, which is actually a socket cover holding two blue sockets. Pull off the cover and put a paper clip or thin wire into the two holed socket to form a circuit. If you did this right, you should see the check engine light stay on when the car is running. Hook up your timing gun to the rubber coil on the distributor cap and the wire for plug #1.

Now, to find the timing marks, look on the pulley on the lower driver side of the engine. You should be able see to two marks on the belt with a timing gun, a red one and a white one on top. To find the actual reading, zero your gun and look to see where the red mark falls against the engine block. This, duh, is your zero-mark. Remember where this is. If you have small enough hands, reach down and mark it with a pencil Now play with the adjustment on the gun until the white mark falls onto the "zero-mark". The reading on the gun should say 16 BTDC +/- 2 degrees which is factory, mine said 15 BTDC. Set the gun at 18 BTDC and loosen the three bolts (careful it might be hot!) on the distributor and move it counter-clockwise until the white mark hits the "zero-mark". This is where that friend comes in handy, one to do the moving and one to do the looking. When it's set, tighten everything back up and shut the motor off before you remove the jumper.
