Hello James, There is absolutely no need to use the command line (except in very special circumstances). You can install new applications from the menu: "Applications -> Add/Remove..." or, if you want a more advanced tool, "System -> Administration -> Synaptic Package Manager".
About the NVIDIA card, I'm not sure what "sli mode" is, but have you tried enabling the restricted driver in "System -> Administration -> Restricted Drivers" or using envyng-qt (which you can install from Synaptic)? (Note that some of the menu names I'm mentioning here may be wrong, as I'm translating them from my Catalan installation, and also that if you look for help people will often send you to the terminal, but that doesn't mean that the same can't be achieved graphically; the terminal is just easier -compare telling someone "write X and press enter" to "go to A -> B -> C, go to tab D, press button E, etc."-).
