You should be able to do Trail 4 (thats a long one), 6, 5, and 3. You could do most, if not all of 8 but I think 8 is closed. Now those trails wont be easy but you should be able to make it through them on your own without a winch as long as you take good lines. I was a newb when we went (had the jeep like 2 months maybe) and we did a night ride and did 5 to 4 up to the ledge and turned around and I did just fine.
Here is an old map link, it does not show where the closed parts are though
