Hello, to address the first of your problems, first some questions; what type of email service do you have (hotmail, Gmail, yahoo, etc)? Do you use outlook?, I ask these questions because back when I did not have a Blackberry, I configured my Gmail account to send me a SMS Text each time I received an email, this way I could check my email knowing there was actually something in it, on the other hand, I found an option in my MS Office Outlook 2007 (tools/options/preferences tab/mobile) that if correctly configured you can receive a notification on your cell phone via SMS text each time you receive an email, so I think this could be why you receive an SMS each time you get an email.
The solution to the second problem is just a click away "
Blackberry for Mac"
