Welcome Todd ! Glad to see another WSK owner in the ranks. You've made a fantastic choice.
I'll offer some of my opinions/suggestions. I'm sure some others will be along with theirs
1. I cover the deflector with foil and / or set a SS drip pan on top of it. I have a 14 inch and 16 inch SS pan I use in my BGE and will use the 16 in the WSK as well. When I use the SS drip pan I cover it with HD foil.

2. I don't' really clean my grates. I will spin the upper grate around when I have coals off to one side to burn them off, otherwise I find I do enough higher temp cooks that the grates sort of take care of themselves. The grates are SS and when they are fully coated, they are what they are. My WSK is about a year old so there are still a few shiny spots here and there but otherwise fully covered with carbonized grease. FWIW, I also have a large BGE since 2011 and I've never cleaned those grates either. Some high heat and a brushing or scraping now and then is all.
3. I use a beach towel in summer to keep the dust, tree droppings and bird droppings off the grill. Last year I bought four that match on sale at costco for 11 or 12 dollars each.
I guess my tendencies are more like "cook a little more, clean a little less" <------ wait, is that a song???
edit: The Genesis 1000 has a bikini, and the others get a beach towel.
