IMO, #1 in your studies should be the Alphabet, then the phonetics of the language, ie how to pronounce sounds standalone, hard and soft (palatalized) versions of consonants, how to connect them with two sorts of vowels, word stress (it's different from that in English), silent consonants, etc. So your learning time in the first month or two should be divided into about 70% phonetics, 10% vocab, 10% basic grammar plus 10% free speaking on the phone, Skype, f2f, etc.
