I'll take a shot at answering your questions.
1) My mantra for activities are to do something you don't mind doing as long as it's low light, low noise and low tech. Honestly reading a printed book (or listening to a book on tape) seems a great thing to do. It can take your mind someplace else, away from performance anxiety of getting to sleep. Old photos can also work well. When you lie down, relive the images. Some people like TV for distraction, but they emit erratic sound levels and also light of course. Plus time seems to go quickly as one program leads right into the next, and before you know it it's very late. Same with computer or smartphone.
2) Resting can feel great for our sore muscles, but remember it is not sleep. So it does not seem to come with the mental restoration of sleep. Also, being awake in bed can lead to a bit of conditioned insomnia, so be very careful of that. And yes, for naps it is recommended they are kept short and early, and only if absolutely necessary. You want to carry as much of your natural sleep drive with you to bed at night.
My $0.02. Hope it helps. I think ultimately you have to experiment and maybe even document what works and what doesn't.
