A good place to start Lol! I was lucky a good friend uses Nikon and went through getting it set up ready.

The basic setup I use:

1x Memory Slot for RAW
1x Memory Slot for JPG

White balance I set to cloudy (I use Auto for indoor stuff)

Image size Large
Image Area DX

JPEG Compersion - Optimal

Colour Space - sRGB
Set Picture Control - VIVID

Active D Lighting - OFF

Image Stabilization is set on the Lens

AF set on the Lens and the Camera

Depending on what editing software you have and how old it is the RAW files used by Nikon NEF may not open, you can convert to DNG files( Search for DNG Converter) or you need a more up to date editor I use Lightroom

Good luck and happy snapping :)
