Welcome to the fray...
Get yourself a binder, and page protectors. Download and print out your drone’s manual; use double-sided printing for this.
Open up your favorite text application and devise a pre-flight and post-flight checklist; gussy it up how you see fit. Print out the FAA regulations from their site. Find and print your state and local drone laws and ordinances. Add your FAA registration (if required), and TRUST certificate. Belong to the AMA, and local FRIAs, add that information too.
Reconnoiter each location that you plan to fly. Powerlines, wires, poles, signs, traffic, people, flora and fauna. Adjust your drone accordingly (RTH altitude, avoidance settings, max flight altitude etc.)
That binder will be a lifesaver. My binder is an amazing, obnoxiously well organized source of information with oodles of yellow highlighting.
