This is kind of fun, especially for you, lol.

If you've only been exploring, you'll probably need to learn about:
Power management (priorities) and turning modules on and off as needed.
PIP management so you have enough power to boost when needed, for weapons when needed, and for shields when needed.
Fire Groups. You should probably have one group with lasers on one trigger and multi cannons on the other, and a second group with your advanced discovery scanner (and if outfitted for serious combat, your KWS).
Have fun!
Speak of the devil ...

On the modules screen, you need to set the priority of the FSD and Fuel Scoop (and maybe Cargo Scoop) to 2. That way they shut down when you deploy hard points. You will also need to turn off your AFMU and hangar until you need them (probably while sitting on a planet).
