Ditto on the weight distribution bars. They will make towing much better with some weight restored to your front tires. You really don't want to be light on the front end. In addition to the links already recommended (and they are really good), read the instructions in your owner's manual on setting up a WD hitch.
Make the dealer weigh the tongue of the trailer for you. I'm sure they have a scale. It will open your eyes. I would be surprised if it were anywhere near the listed dry weight. And remember you're just going to add to your tongue weight when you load your trailer, so size your weight distribution bars appropriately. 800 lb bars should work, but you may be in the range for 1000 lb bars.
No need to feel intimidated. I'm more intimidated backing up my utility trailer than my toy hauler. You get used to the size pretty quickly. If you get it set up right from the start, then you can relax, go camping, and enjoy your trailer. The point of a vacation is to be stress free. Have fun and enjoy your rig.
