Not sure how it works over there, but like you said all you need is a USB cable for the phone and the software, which you should be able to download off the Motorola website...after you have that it should be as easy to transfer music, pictures etc to your phone. But you’re right, buying ringtones and wallpapers for your phone is a waste of money.
V3m is not one I'm familiar with though...is it one of these?

If you have expandable memory on your phone (i.e. if it has a memory card slot) you should be able to get an adaptor that will allow you to put the memory card directly into your memory card reader slot (if you've got one on your laptop) or an adaptor which will allow you to put your memory card into it…that will then go into your USB port, which basically will act like a USB flash drive and again you can drag and drop files to and from your computer.
Try and find out which way will be easier and which model it is and maybe I can see whether I can find a few bits and pieces to send you, that will help you out.
