Welcome to the site.
A few things about Nationals.
1) Go there to have fun.
2) Don't lose the pocket. What I mean by that the people who bowl the best there don't try to hook the lane. You can't. Starting the ball in and getting the ball outside of 10 is a recipe for disaster.
3) A spare ball is a must. Use it and use it often. Straighter is greater for spares. Hooking the ball into spares is a good way to have a lot of opens.
4) Have fun. Why do I mention it twice? Because that is the main reason for bowling. Having fun. I have been a few times and I find that if I start getting upset with how I am doing, it just gets worse.
Now, for the lanes. I haven't talked to anyone coming back yet but, in the past, here is how I have played them. During team, tart with your mark around 15 and have your break around 10. Use your ball that can eat some oil. That is where a majority of people will be playing. A dry spot will start to form at 10. Use it as a bumper. As the games wear on, you will start being able to use polished equipment. During D/S, people can get the ball outside of 10 maybe to 7-8 from the inside. Getting it outside of that is a good way to get a 3 count. I have seen people with even rolling equipment roll straight up 5 and have success. Out there, you don't want a ball that is too jumpy.
