Hi,
Should I contact Golden Age of Railroading about using their GN SD7 models in my scenario?
I think that clause in the file library is meant for repainters so they don't accidentally clash with somebody else's rules and copyright. With uploaded scenarios, simply don't include anything but your own files (the scenario folder from the route). Then the equipment you use is entirely up to you and no extra permissions can be required from you.
Also when packing the scenario into a .rwp file, do I need to include the following?
I recommend creating .rwp files for scenarios and include the whole folder for the scenario. Those small .md5 checksum files are (mostly? only?) needed for the Career scenario system, but why complicate things and filter out files for each upload.
should I have scripting in my scenarios?
That depends on what you want to do. I find that scripting is unnecessary to create good and entertaining scenarios, but it opens up new possibilities that aren't available with the in-game editor. You can do fun things like pop up html messages (with pictures), manipulate the player's camera, check and react to the player train's state (speed etc.), or even manipulate the player train's controls (throttle, brakes, etc.). It can get complicated quickly but it's your only option if you want to do things like I just mentioned.
Here's the official reference guide:
