Replacing tailight bulbs on a 2001 Spectra

Hi I just got a 2001 Kia Spectra 5 door.

Last night I noticed that one of the rear tailights is burn out. I was expecting some sort of a access panel from inside the trunk but I found none. I saw a couple of screws holding the Taillamp assembly to the car, Do I need to unscrew the tailight from the car to change the bulb?

Also, is there a place that I can download the user manual for this car?

thanks
