Comparing Values and scorecards based on a lookup table

I have 2 tables of data (see below example), 1 with a listing of a bunch of reviews on sports with a star rating.  I have another table thats a reference that says what sport i should benchmark it against.  In other words, what i want to compare that selected sport to.  

I would also have a slicer that allows me to choose a sport of choice.  I would prefer to use the reference table as my slicer.

Question 1: How do I make a chart of average Star Rating that ONLY shows the chosen sport and its Benchmark? It would look something like this:

Question 2: How do I make a scorecard showing each sport compared to its Benchmark? For example, below and red or green is calculating by comparing star rating vs the benchmark's star rating. It would look something like this:
