what are live chess tournament points for?

There are three kinds of points at play in a Live Chess tournament:

1) rating points - all Live Chess tourneys are rated, so just as though you were playing a rated game outside of a tourney, rating points are there to win or lose,

2) score points - if you win a game in a Live Chess tournament, you are awarded 1 point. If you draw a game you are awarded 1/2 point. If you lose a game, you are awarded 0 points. The player with the highest number of these points, wins the tournament, unless ...

3) tiebreak points - unless he/she ties with another player with the same number of score points. To break such ties and award a clear first place (and other places) to the best performing player in a tournament, chess.com award tiebreak points to you based on the play of your opponents. If all your opponents - the ones YOU played during the even - score well in the tournament (win and draw games), then you will receive a larger number of tiebreak points. If two players tie on score points, the player with the most tiebreak points is awarded that place over the player with the fewer number of tiebreak points.

Pretty complicated it can seem. But I'm sure you'll get the hang of it in no time.

Do you get rating points on chess.com for winning a 15/10 Swiss tournament, for instance?

To clarify, I mean for winning the tournament, not for winning individual games

Rating points are gained and lost only by winning or losing individual games. This is how rating points work here (i.e., chess.com) and in over-the-board tournaments.

As a follow up question… can you or anyone else tell me why the second win in a live tourney is worth 3 points? 

That's just how winning streaks are scored for arena tournaments.
