For a first-time player, I'd recommend Creative as well so you don't worry about border pops (don't build Stonehenge if Creative). Very easy-to-use trait. Financial is also very easy to use. Organized is certainly easy to use, but not much use on low levels. I'd also avoid Rome - too easy to rely on Prats.
That said, I'd get away from specific traits quickly and try a variety. Each trait is used a little differently. Some are stronger than others, but all give an advantage. Some, such as Philosophical, need experience to use well.
I suppose you could try Toku so you're not dependent on any economic traits. Most people think he's a very weak leader, although not as pathetic as the AI plays him. Provides a nice intro to using Macemen in war, however.
