The ranking sounds about right, with the exception that I'd swap the last two positions. The Italians seem a little unstable to me at the moment.
Loew put Gomez in the team because of his skills of game development. On first look, it seems that the only reason he's in the team is his four goals in the UAE friendly match... that's not saying much, my grandmother could win against them too.

You're right, he has to show his stuff in ZA and score at least one or two times or he'll be out. Thing is, we have a number of talented players in the Bundesliga but very few with enough power for the national team, so Gomez' nomination was inevitable, at least in the current situation. The juniors are a problem... but that won't be Loew's headache anymore after ZA when he will resign (at least all signs point to it). Let's see who comes next... I want Paul Breitner!!!
And Neuer... he's young and highly motivated, that's all I can say, they really love him in Gelsenkirchen (Schalke).
What about his name, how does it sound in English? "Newer"?
