The P-11 is only a pocket gun for those with deep pockets... but since you're a future millionaire, and not a current millionaire, I'd stick to a P-3AT for pocket carry.
Sorry... I had to do it.
Yes, many people here love their P-11s, and PF-9s. They are good guns for low bucks. Neither is pleasant/fun to range-shoot daily, and both are large as pocket-guns go. The PF-9 is very well suited to IWB (Inside the Waist Band) carry, because it is very slim. If you're going with a gun as thick as the P-11, your better off saving your nickels for a M&P, XD, or Glock.
As a beginner-shooting, you WILL need a gun that you can shoot frequently for practice, practice, practice. So I agree with the 9mm. For close in, defensive work, the 380 is fine, but only if you can be accurate with it. The 9mm is better for home defense, but both scenarios are close-quarters.
