For # 1, are you saying that you want the parameter options to be side by side rather than one on top of the other? If so, I think you'll need to change the parameter to a single value dropdown.
For the top/bottom 10, I'd take a different approach than what you're doing. I'd start by creating a parameter called Top or Bottom.
Then I'd create a calculated field like this:
Top X Value
// Allow us to get the top or bottom X for Avg time to fill.
IF [Top or Bottom]="Top" THEN
[Avg Time to fill]
// This will make lower numbers bigger.
-[Avg Time to fill]
Then, I'd set up Job Category as a filter as follows:
Finally, I'd remove the filter on TOP10.
Then, on your dashboard, change it to use the parameter instead of the filter.
See attached. Note: I only made the change for the Time to Fill sheet.
