It doesn't make much difference to me how you spec out your bike but I'd stick to basics before going hog wild with farkles.
Why bother getting rid of perfectly good gauges? You're going to need that $$$ for some other things, like dual front brakes, a bar mount master cyl, an LED tail light so that you can be seen after dark, lower/different bars, parts to rebuild the front end, new shocks, MUFFLERS, maybe some small parts, gaskets, etc.
Once you have the basic stuff squared away, the rest is mostly cosmetics but you need a safe, sound bike to build on and you bike will be much better off with MUFFLERS. Your valves will thank you!
