We get wicked wind on my 'slope'-- redistributes everything for me, too, regardless of what I do.
In the spring I clean up deep, soggy leaf piles (and garbage) along walls and in alcoves/sheltered spots and relocate it to finish composting somewhere.
I do leave most all my perennials standing shaggy for winter. It helps to hold whatever I'm using for mulch, and they kinda mulch themselves some that way as they die back. It looks like crap but I get better survival for the herbaceous types.
