Aww that's a super nice bike. My friend has a Honda CB500 actually -- the body style for the 750 is very similar! And thank you -- I see a lot of riders on the road stop at a red light and go into neutral but I have always heard to stay in 1st as a JIC. I'll keep that in mind. ))Sounds like you are progressing nicely. Don't lose that good habit you have of keeping an eye on what is going on around you. Lots of people get in the bad habit of being in neutal when stopped. Keep it in first with your clutch disengaged and keep an eye on what is happening behind you until you know for sure the car behind you is fully stopped and the car BEHIND him/her. This could save you one day.
Awesome choice for your first bike. I have thought of a newer Bonneville as an eventual replacement or second bike to go with this old girl.
