Salaam,
I think that when one is learning languages, pronunciation is one important aspect. It is always good to try and pronounce the words as correctly as possible.
However, I do feel that there might be an over emphasis on this, in respect to the Quran.
What is unusual in the case of Quranic arabic, is that unlike when one learns other languages, this one (in general) is learnt without understanding the meaning of the words in your own language, so you are effect learning without learning.
Although ideally, one should do both to get the full richness of its beauty, I would always favour learning the meanings over pronouncing the words.
And for Sardar Miyan, I can recommend going on YouTube and typing in 'Tajweed'. You will find many lessons on this staring from the alphabet onwards. I have found this very useful.
