I am afraid that I can't answer your specific question(s) as I had the dealer install mine. However, I must caution you with this: I bought the Rizoma sport grips and bar ends for my Monster and had AMS in Dallas install them. They later called to say that they were shorter than the stock, so they would have to cut the bars so that the end weights would be flush against the end of the grips.
I opted not to and it isn't noticeable when riding since my gloves cover it up and you would really have to look closely when it is parked. Either way, you might want to measure any replacement you are considering just in case.
Also, make sure the ends aren't rubbing the grips as it could prevent the throttle from twisting back to idle if you were to suddenly let off the gas or, heaven forbid, get thrown.
