I love Ergon grips. After I buy my touring bike I'm for sure going to either upgrade my commuter or buy a new one with some Ergons on it (i work in a shop otherwise I couldn't afford this option).

I use bar ends on my current commuter and like them a lot. I don't wrap them at all, but probably should. It's pretty easy to fit on either a mtb style grip or wrap a little bar tape around them. If you really want to get crafty you can take an old bike tube and use that as a handlebar wrap. Works well as long as you're not allergic to the rubber or the latex-ish powder used on the insides of the tubes.
