Answer

Let's look at each question:

"I am promoted to..." = Incorrect
"I was promoted to..." = Correct
"I got promoted to..." = Correct

And yes, It's perfectly acceptable to just say, "I got promoted" or "I got a promotion".

Answer

As it is in the past, It is more appropriate to say to friends informally ,  'Hey, I got promoted'. They may ask about your new status and you can say, 'Well I got promoted to Assistant Manager'. It doesn't matter really, you can say it all in one sentence as well, "Hey,  I got promoted to Assistant Manager'. 
If you are talking formally or writing it on your CV you should say/write 
In 2009 I was promoted to Assistant Manager.
