I will appreciate if you open up separate threads for the additional questions. That will help us to serve you better and other customers to find the solutions if they have the same problem as yours.
If you want to have the Bar as Sticky mode, try to make that Bar the top bar of the header and remove the Absolute positioning from the other bars, that will cause the other bars to sit after the sticky bar. If you turn on the absolute option, you will have the bars go behind the sticky one.
I suggest that you check our Header Builder video to get a grasp of the tips and tricks of the case (I know it is a long video but worths the overall knowledge that it gives)
