I'm not 100% familiar with real tactics, but if your Stukas are diving from 3000 meters, they would be pulling out at 1000 m and then bugging out as fast as possible.

As far as I'm aware, they only stuck around for ground attack with definite air superiority, and even then they probably would have arrived at low altitude to start, making a more conventional bomb run.

AB bombs can be dropped from either a dive or level flight, but you will want to set your timer accordingly.

The Ju-88 cannot dive like a Ju-87. You dive it by going down 45 degrees and using the specialized sight. Rolling inverted and then pulling vertically down was prohibited due to the stress it caused. It was also unlikely that 4x SC 500 would be used in such an attack. If you use the correct approach method, you will not need more height than a Stuka to dive bomb, as you say; The Ju-88 can do it easily at 2000m or even 1000m.
