Hi Ghosty,
Looks like Curious Aardvark already covered most things, but I'm going to give you some literature regarding calibration and some basic (yet very important) things such as leveling, getting materials to stick, getting good print dimensions, etc.

You can start at the 'Bed Leveling' parts since the motherboard / stepper calibration should not apply to you if you've got an assembled Flashforge.

Also, as CA mentioned; lots of stuff is already mentioned on this sub-forum;
Everybody has the same 'problems' with printing when they start - just keep going at it, use your brain, and ask people if you need some advice and you'll be printing whatever you want to print in no time!
