One thing to remember is Vegas is just like any other major tourist city. I've been visiting Vegas a couple times a year for nearly 20 years and I've never been a victim of a crime, but that doesn't mean I assume it can't happen.
No need to be terrified of anything happening, but no reason not to be smart. Keep your personal affects close to the vest (especially when outside), be aware of your surroundings, be aware of traffic when crossing the street at ground level (there are pedestrian bridges at some corners that you can use to avoid the traffic), ignore strangers on the Strip that try to hand you/sell you something (though nothing wrong with being friendly to fellow tourists), and utilize the hotel room safe (though don't leave anything behind).
Also, keep in mind that Vegas is a service industry town that runs on tips. You can decide for yourself what constitutes a proper tip, but a couple bucks here and there will be appreciated by the hotel staff.
As for what to see/do, a walkthrough of the Bellagio hotel is an absolute must for a first time visitor. A beautiful property and the atrium display is always impressive and worth spending time appreciating the time spent to put it together. From Bellagio, you can walk to Aria and Park MGM without having to go out on the Strip, which is nice to spend some time away from the heat (even in September in can get into the 90s and low 100s). Note that Park MGM is a smoke free property which is nice if you want to spend a little time there. Park MGM has a nice little breakfast/lunch/brunch spot called Primrose, and they also have an Eataly and some other nice restaurants on property.
Enjoy your time in Vegas!
