I will be honest and say that if I'm going club racing I don't take any with me. Once I have the car dialed in to the local track I don't feel the need to bring them along but if I'm going somewhere new then I bring a small assortment of weights in the general area of what's currently in the shocks.

At a minimum you should bring the oils you are using in case you have to rebuild something, and if you are doing a brand new set-up, you'll want to bring everything you've got.
If you're a high level racer going to a new track, you'll probably bring a variety depending on what you are expecting. But you already know what range of oils work in your car, so you probably only bring a limited selection.
I am in favor of buying one of each. You want to have options when tuning. Even if you don't use an option, you want to be able to experiment with a wide range to find what is too stiff and what is too thin.
