This solution is for your quick filter problem. I will write solution of your other problem after sometime.
Here are the steps-
1) Put filter one in filter (Product Category)
2) Put second filter (Product Subcategory) & choose only relevant value. Before adding 3rd filter first click on second parameter & choose "Add to Context" option.
3) Now put 3rd filter & choose only relevant value.
Hope this may help!
I previously posted a similar question which got an interesting answer from Jonathan Drummey which might be a technique you can use. That said, I haven't tried it myself yet, but hope this is something you can use.
