There are no connectors that fit the reprapdiscount display, so are you sure you have that display and not another? The sparkLcd also have 128x64 pixel and fit onto the ports of the RADDS. You will see that they do not have an sd card - the one on radds is used here. The reprapdiscount sd card is made for 5v and uses a level shifter but ardiono due needs 3.3V output. No idea if this would work if you connect these pins. Therefore there is also no out of the box configuration for that combination.
There is in any case no need to install additional libraries. All required libraries are included in the sources. As long as you only change configuration but use same firmware version, downloading new Configuration.h is all you need to recompile.
