The only thing in your control is actually # 1, that is, you can record errors. You can do this through http://developer.apple.com/bugreporter/ for all Apple products, including the IIRC SDK.
Your other two points are not so simple, since you can only see your mistakes. You just need to believe that when Apple launches them through sorting so that your correct flag duplicates. Some people include the Radar URL for their mistake when setting n to mailing lists, etc. This URL only works for Apple employees, but the hope is that if you easily find your mistake, it can be fixed sooner.
