Tailwag, it's not clear to me whether you are making out the rings or not. I've been trying to with my 20x80s (yours are better) and my 30x100s and reckon I'm close - I certainly know there are rings there, but I'm trying to clearly see the gap between rings and planet and the shadow on planet/rings. Just need a good night of good seeing in the next weeks.
However, it helps if you know what you are looking for
See this thread for a view of what Saturn should look like as it crosses the meridian

Ignore all my talk of north and south poles - I just didn't know what I was talking about and now I do (Huh! Pull the other one!)
Re moons - forget all the maths - use sky view cafe or something else - it'll give you an illustration of the moon locations at the time you are looking. I've found it great for the four Galilean moons of Jupiter and for Titan, the only moon of Saturn I've spotted so far. Just remember you may have to flip north and south and maybe east and west.
