Traits don't usually have any prerequisites unless they specifically say they do. Traits are a fairly commonly used alternate system for character creation. For most of the games I play every character starts with 2 background traits. It's basically up to the group (or the GM) whether you want to use them. If you're not starting with them you can pick up 2 traits with the ADITIONAL TRAITS feat. If your group doesn't normally use traits it might be worth checking that you can take this as a feat.
If you do use traits then remember you can only take one trait of each type (or subtype for basic traits). This means that if you take Overwhelming Beauty you can't take another trait marked: "Basic (magic)".
