For your last question, I don't see the point of a 10 round 9mm. One of the benefits of a 9mm is capacity. If you don't have that, why not go for the bigger bullet.
I personally own the Magnum Research Baby Eagle in .45 ACP. It is a great gun. Light recoil for a .45, natural pointer, reliable as a Glock, SIG, or Ruger, and holds 10 rounds. Decent gun and costs maybe slightly less than a Glock so it won't break the bank.
If budget isn't an issue and you can find one, I really like the HK 45 but didn't want to spend the money.
If you want a more common brand, I was pretty close to buying the S&W M&P in .45 ACP as well. I didn't want a striker fired pistol though, thus the Baby Eagle. I can't personally attest to how good it is, but my research was generally positive.
