Me personally, I would modify the top of the triple to take risers, and then slap on a set of dirty bars, some nice chunky ones like the Pro Taper fatty's. Obviously you will have to buy the riser's accordingly.
There are a lot of different styles and setups for headlights - some guys have even used spot lights from a car - so only once you have decided on what you want, can you then start looking at how to mount everything. E-bay, etc are good places to start looking. You could even get ideas from the members here by looking at their bikes.
There is a thread here about gauges. I will try and find it and send you the link, and don't forget to check the classifieds.
Hope this helps.
