I was going to install the side molding as one of the accessories on my Touring, but the one I found in the color that I wanted, Cosmic Blue, already had them installed by the dealer. I did, however, add the lower door trim myself and I think it looks really nice
I installed lots of the other accessories myself, too. It's nothing to hard to do if you're a bit handy and have the tools and the time. The accessories no longer come with installation instructions, but plenty of the accessories dealers on the web have them available so that you can review them ahead of time and decide whether or not you think that you can handle it on your own.
I bought my accessories at
http://accessories-honda.com. They are a dealership out of Ohio and had the best prices that I could find. It took just over a week to get all of the stuff that I ordered and it all came in just as expected, so I would recommend them.
