Help with USB Cable & transfers

OK, I thought this would be alot easier than what it is... I just got a new Motorola E816 (basically the E815 in black). I got a USB cable, and I have a bluetooth that doesn't seem to work, and I can't unstall the damn thing to reinstall it (this worked b4). So i will just stick to the USB for now on trying to get to work.

I assumed that all you would have to do is open up a file and simply click and drag to the phones "file" well that obviously would be too easy. So Ive read a few things and think I need to download the MPT to get it to work with this phone. So i downloaded it and it works as far as I know with the USB. But I dont understand what you need to do to click and send a file? Im lost, and about ready to forget the whole thing.

Is there and easy solution to using the USB cable and my phone to transfer songs and photos from my computer? Do I really need a special software package? This is frustrating to say the least.
