I am an Indian national residing in & working in Australia on work visa (not a Australian Permanent resident/citizen).

I have a got a good job offer from a big organization in Berlin. My Salary is promised to be around 50,000Euro mark. I have a university degree recognised as H+ in Anabin database. 

My marriage date is fixed in Feb 2015. I would be able to get a certificate only at that time. 

Now whats my pathway to German work permit & bringing along my wife in March 2015. 

My potential employer is keen to get me in asap. So, I have been told that, they will do all they can legally to get me & spouse in. 

i) Is it possible to get Blue Card by Feb2015, if I apply for it on 1Dec14?
ii) Can I apply in German embassy in Melbourne or Caberra here in Australia or should I be travelling to India to lodge & attend the interview.
ii) If I have a blue card, do my spouse have to show A1 competency in German ?
iii) What is the processing time ? I could get the marriage certificate by lastweek of Feb 2015. If so, when should I apply for Spouse visa ?

Apologies for too many questions. I am confused now - not sure if I should accept the offer or not. 
Your help is greatly appreciated. 

Thanks,
Arun
