The lack of Sequence presets looks like it's running in trial mode perhaps, otherwise could be a bad install. Did you uninstall your old version completely and run Adobe Cleaner utility before the CS6 install?
As for no audio, please try using the Media Browser to Import your clips into Premiere, should find a tab for this at lower left of Premiere interface. This is the preferred method for tapeless media import.

The fact that you are missing presets means that there are a series of codecs that were not properly activated. This is also the cause of your missing audio.
Ann's recommendation of reactivating should resolve the issue. You also may have to restart Premiere twice after activation before the presets will appear.
I dont know what i did but it seems to work now.
I was going shoot my self literly coz of this problem, B'coz i never stuck for long time in any bug like CS6 audio and presets missing bug......So it sorted it out itself i just shutdowned the system last night and went out.
And 2day i just turned on the "torcher machine" and loaded PR, all the presest are available audio is fine i dont know what happend i really dont.
Your computer was able to connect to our activation server, and then resetting it made Premiere reload your codecs -- we have a document on this issue now.
