Ear plugs are a good idea. If I ride too far without them I get the ringing sensation for a while. Every little bit of hearing damage adds up over time. I've never tried music. I think there's more danger and distraction in fooling with an Ipod or whatever while riding than the actual noise. Sing to yourself - I sound pretty good inside my helmet.
For the other gear I have a Vanson jacket. Bought it on ebay for pennies on the dollar. You can't really hurt this leather, so buying used is a good option if it's just seen normal use. Have an Arai and Shoei helmet and am overdue for a new one. That thing with the built-in sunshield looks like a good option. Gauntlet gloves with kevlar knuckles.
Jeans and boots are my weak points - it will probably catch up to me one day. I have some cortech pants and Alpinestar boots but don't wear them 99% of the time. I should. I used to wear full leathers on those early Sunday morning rides. The ultimate protection, but talk about a cop magnet.
