Another thing to think about is if you are going to stay with a touch pro for a while, or if you will be making the move to an android phone in the near future.

If you are going to move to android, it would be worth importing the contacts to google, that way when you get the android phone you just have to sign in with your google account and it will import all of your contacts automatically. Until then, you can sync your phone with m.google.com and have it pull all your contacts to your WM phone.
