Ticket question.Any help?

Hi all.I want to ask.I've got 2 "Stehplatz-Innenraum".Can you please tell me what is the difference betwwen the previous and "Stehplatz-Rang" ? It is for the Munich show in Germany. The first costs more money. Are those tickets close to the stage?Can i get in the pit if i get there early and there is still space in it?
And last if you got standing tickets how many hours ahead will you go to be in a proper place close to the stage? Case i am thing something like 7 in the morning!!!!!
Thanks in advance.

There is a huge different between the tickets. The "Rang" ticket is in the tribune next to the seats, and the other is on the field.
