You can use the diode setting on your multimeter to determine the anode and the cathodes. You can also test this by using a power supply in series with a 100 ohm resistor. When you connect the power and it lights up, you found them.

The circuit you are asking for sounds an awful lot like a school project...? Nevertheless, I am sure you can find a schematic to help you figure it out if you search on google image search.
