I was on a website and could not determine if its usage of conjunctions was correct:

The website has this to say about using and as a conjunction:
To suggest that one idea is in contrast to another (frequently replaced by but in this usage): "Juanita is brilliant and Shalimar has a pleasant personality." My problem is that I believe a comma should come before and. Both of the sentences could be split into independent clauses; however, they may be wrongfully represented independent clauses.
Another part of this website talks about correlative conjunction. I was looking at a part of the website and believe that passive voice would have been a better consider. Otherwise, a comma was necessary within the sentence to take away ambiguity.
But is my concern a concern of style?
"Whether you win this race or lose it doesn't matter as long as you do your best." Shouldn't this sentence be as follows:
Whether you win this race or lose it, doesn't matter as long as you do your best.
