Hey no worries one bit, learning new stuff is half the fun with this hobby. When the 737 came out I made a simmer-to-simmer manual for it, might wanna consider giving it a glance over. It adresses SID/STARs too.
I understand you use Simbrief, right? I’d recommend installing the following little add-on as well to ‘fetch’ your simbrief flightplan in the sim. Scroll all the way down in the app and it will list your SID (departure route) and STAR (arrival route), together with the runways Simbrief calculated for the flight.
