For looks you can't beat the Corbin Beetle bags. Not on your list but a MUST have are Rivco Exhaust Flange Covers. Available from http://www.newr3.com I've had Triumph guards, saved my bike, now I have the Rivco guards. Why I switched is beyond me, but both seem like they do the job. Maybe the $25 diff was enough to sway me at the time.
Yeah, most of what is listed above.... Also would recommend the CAT bypass.... About $365.... That plus the associated Triumph retune will remove some of the limiters in the ECU and will give you a marked performance improvement and throttle response... Addtion of the Tuneboy program for the ECU will make it that much better....
