My comment pertains to your last question mainly:
I think it really depends on the direct leadership above you. If you have a cold, uncaring boss that only wants numbers, having top numbers is the only way to get in his/her good graces. If you have a boss that values patient and employee relationships, maintaining good customer service as well as keeping your employees happy and speaking well of you will help you there. Honestly, it seems the only real way to move up the corporate ladder is to be a chameleon, see what your boss wants, and deliver that. In general, enthusiastically delivering on the corporate initiatives (regardless if they make sense or not) is the best way to be noticed.
I personally have no real desire to move up the ladder beyond where I am at as PIC. I did a corporate rotation in school and that environment had no appeal to me (expected to be artificially enthusiastic about everything, never question any decisions or proposals brought up by upper management, your aptitude is almost solely judged by numbers on a spreadsheet, etc). I really just try to run my store as smoothly as possible, give my boss honest assessments on the store's performance as well as thoughts on new corporate initiatives, and try not to be a general pain in the ass. Having some empathy towards what is expected of your boss and letting him/her know you are aware of these things seems to really help in building a mutually beneficial relationship. I am fortunate I have a great boss overall.....I know for many they aren't so lucky and their success solely depends on meeting corporate demands/metrics.
