Welcome to the club, it really depends on how you use you camera, how much you like to edit your pictures yourself, and how much understanding you have of computer software for processing your pictures, in particular if you use the RAW setting in the camera to shoot with.
If all you want to do is to let the camera do all the work and then just to download your pictures and view/keep them as they are, then i would suggest - Jpeg Standard Color, Fine Save setting, and Large setting, I would also suggest setting things like - contrast, sharpness and noise control to medium levels, this is a good level playing field from where to start from.
When you get more interested in doing more alterations to your pictures within your pc, then you could choose the RAW mode in your camera and with software like Lightroom you could then play around to your hearts content as your original RAW file (like film negs) are left un altered.
Hope this helps a bit
