Fuel Scoops are a piece of equipment that let you fly into the corona of a star (just outside of the green line you see when you get close) and refuel your ship. Its a massively important piece of kit if you plan to explore, since there's nowhere to land out there in the black. To use one (provided you have one...they don't weigh anything and the lowest ranked ones are amazingly cheap) just fly towards the star until you get a message that you're fuel scooping, and kill your throttle while making SURE that the centerpoint of your canopy is ABOVE the green line (you don't want to drop below that green line, unless you feel like getting dumped out of supercruise and BBQd). Now just wait for either: a) your fuel tanks to fill (it will give an announcement that scooping is complete) or b) your ship to overheat, in which case punch it, get away, cool off, and come back for more.
As for finding a station...look at your right hand panel (I use the head look key, since it feels more "natural" and immersive than pressing my preset button...but that's just me) and you'll see a list of everything in the system you're parked at, along with a list of all the nearby systems. Just select a station (they're normally named with words like "Dock", "Port", and "Outpost", although some are a bit stranger, although you can always tell because there will be an icon showing a station graphic depending on what kind of station it is), hit "lock course" or "lock course and supercruise" if you're parked, and then follow the tracker on your screen (the little circle with the cross on the upper left of your radar gives direction to your target, move around until its a white dot in the center...if its a black/white circle, its behind you). Watch your speed on approach too...punch it to max throttle for the main journey, and pay attention to the countdown timer of when you will arrive. I have a 75% throttle preset button equipped, and the moment it hits around 10-8s remaining I press that...it will ensure you slow down enough for a safe stop at the station (just wait til you get "disengage ready" and press your supercruise key...mine is bound to K, but you can set it to whatever you want). Then its just a matter of landing...the landing tutorial will teach you that.
