I also had that phone. It was that bright red Verizon special color and one of the best looking phones I ever owned.
As for the topic at hand, I wouldn't bother rooting it. I would keep it as is and simply add the music and videos you want to it, playing with the stock gallery app (or perhaps a third party app). I would also uninstall any bloatware you can to save on storage space.
I'm not sure why you want to root. It doesn't drastically change anything in and of itself. It can allow you to make extra changes that a normal user can't, but I question the necessity of that for your purposes.
