I've tried a multitude of sauce recipes, but do find that simpler is better. It all depends on which tomatoes you bought. If your canned tomatoes do not have salt in them (most do) then you definitely want to add some salt. Some canned tomatoes come packed with basil. That may be enough seasoning for you.
What I would do is hand crush the tomatoes, add a clove or two of crushed garlic, and whisk in a tsp of Extra virgin olive oil + some salt if the tomatoes aren't canned with salt.
Once you try that, you can expand your ingredients:
Oregano and basil are good herbs to get started with. I prefer dried oregano and fresh basil.
A pinch of red-pepper flakes would be good too.
Also, penzey's spices makes an excellent pizza seasoning:
