Admittedly I had to look up the lingo on some of those...I'm impartial to handlebars that can be adjusted within the risers so the bootleggers & streamliners are out since they're glorified "wishbone" style handlebars that bolt directly to the upper tree. Simply put if you don't like the way they feel, i.e. if you'd like them better tilted up or down, you're screwed.
I'm biased toward apehangers, but nothing too tall. I had to google "rabbit bars" and they appear to be what was once referred to "buckhorn" handlebars. Overall they're comfy but you have to get used to the "steering wheel" stance for your hands instead of the traditional "motorcycle stance".
I've done a few rear fender mods...first up is the novel idea of actually BOBBING the rear fender, granted I bobbed the front portion (near the engine) and rotating the fender forward as opposed to the traditional method of lopping off the back tip:
I wasn't wild about how it didn't quite radius-match the wheel so I swapped it for a 750 Aero front fender that I reversed for the rear wheel and bobbed the valanced portion off teh rear of what was once a front fender thus leaving the forward portion (ignore the sawed-off head pipes, I had intended to slip some mufflers onto them but I got rid of the bike long before it was finished):
I really liked the way this one turned out. The 750 Aero fender is made of ABS plastic so the added unsprung weight was minimal compared to mounting the shortened stock metal fender in the same fashion. You can see the piece I cut off that fender in the background:
If you can weld then section/shorten the stock fender:
Again, ignore the sawed-off head pipes as the exhaust system is far from being complete on this project.
All it needs is bondo/sanding/paint, although I may spring for a new set of fender supports and try something different for the mounting as I'm not wild about the way those lined up via sectioning. I'm still not committed to this, but I want to see how it looks finished with the replacement fender rails before I decide between this and the swingarm mounted Aero fender above.
You mentioned ditching the front fender. If you're fully committed to this, and you don't find the need for a fork brace, then get rid of those nubs on the lowers. The fork on the left side of the pic is intact, the one on the right has been smoothed down:
Polish or paint afterwards. Coincidentally this also allows for the 110 series front tires that have questionable/hit & miss clearance issues with the nubs & fender bolts, and no doubt a 120 series hoop if such a beast exists for these 18" wheels.
Other fun stuff that can be done...polishing the aluminum bits:
