Supa's on a good page there. I always use a razor blade to clean the exterior glass. Just habit. It's works very well. Unfortunately, I have very hard water at my hose and about every 2 years have to polish the glass because it gets this nasty film that looks like gasoline and water mixed. You know, the kinda weird yellow/blue/purple ripple. As for the bugs, I wouldn't use anything like the goo gone or any of that crap. IT WILL remove the wax and polish you just worked so hard to apply. Take some carwash concentrate and rub it on by hand. Be generous here. Let it sit for about 20-30 minutes, then take a small amount of carwash and water mixed and you're washmitt or sponge and agitate it. Should safely remove all the bugs and still leave the polish and wax intact. Oh, for rinsing, I take a pitcher and pour the water on that area only to avoid wetting the rest of the car, or just wash the whole damn thing anyways.
