What's the purpose of the salt? I'm from the land of putting salt on ice to break it up thus my confusion.
Basically, it keeps everything colder for longer.
Salt does make ice melt, that's why they put it on icy roads to break up the ice like you said. But while the ice is melting, the salt also cools everything even more. Because heat energy is drawn and released from the ice in order to fuel the salt/melting reaction, the solution becomes even colder. Since saltwater has a lower freezing point than regular water, you then have a liquid that's even colder than the ice was. So while your ice will melt more quickly, your things will be kept colder for longer.
Make sure you use coarse salt (aka ice cream salt)!

So after reading all these posts and doing some of my own research, there seems to be a bit "OMG don't put dry ice in your cooler or it will be a bomb" on other sites. Has this ever happened? Are there tips and tricks to keep this from happening that I'm missing? Since I have a 12 drive just to get there, I'd like to make sure my stuff stays cold but I also don't want to blow up my rental car.

It'll only be a bomb if a lot of water comes into contact with the dry ice.
Keep it in the plastic bag it's sold in and you'll be solid.

Last year I just packed a couple of extra Ice chests with nothing but ice in them and it lasted until I got home monday Night. I filled 2 Big Ice chests and a small one right before we left. Only put water/food in one of them.
Another factor to think about is the type of cooler itself. In 2010, I brought 2 coolers with a layer of dry ice (pellet form) on the bottom, a towel on top of the dry ice, frozen water bottles on top of the towel, and then my food-stuffs on top of the frozen water bottles.
The first cooler was a cheap brand without a lot of insulation in the walls. The dry ice in it lasted 2 days. No biggie since we had allready eaten/drank what was in that cooler. What was left was moved to the second cooler.
The second cooler was pretty robust and had really thick insulation in the shell. That thing was so cold that it was freezing the food and the dry ice was still present when we drove back home 4 days later!
As for ventilation. Most coolers have a drain plug. If you are planning on putting in regular wet ice as well...DON'T! Water + dry ice = rapid melting of the dry ice and the production of A LOT of carbon dioxide. If you are going the frozen water bottle route, then you will be just fine. Leave the drain cap off the cooler to vent any excess CO2.

This'll only happen if your cooler is air tight, and I don't think any coolers are. If you are afraid of your cooler exploding, one easy solution is to unscrew the drain plug.
