Answer 1

Installing apps using Blackberry Desktop Manager should not use any data from your data plan. Once you install the application, depending upon what it is, it might connect to the Internet and cause data usage.

best way would be to contact your service provider.you dont wanna get charged over $5000 like someone was for transferring files from phone to pc and pc to phone.
