HELP!! Connecting Blackberry to PC

Greetings All, First day with a Blackberry (8310 Curve) and I am trying to figure out how to put my music from my PC at home on my Blackberry. I connected Blackberry via USB cable but I think I need to download a program to my PC in order to drop my music into my Blackberry. Also, can I download mediasync to move some of my music from iTunes to phone. I'm sooo confused right now and I am not computer savvy at all making this that much more difficult. Thanks in advance for your help and any tips you are willing to share with me. Please just speak in layman's terms. :confused::eek:

Do you have a media card installed on your BB? I have used DM to put songs/files/ringtones/etc. on mine here thru it. Used Media & dropped/dragged files onto the phone.
