The Arabic language..hmm
my advice would be to try to listen to as much arabic as you can if you got a satellite try and pick up al-jazeera for example and see if you can find some where where they explain how to position the tongue when you say the g in arabic.
also remember that arabic only has 3 short vowels and 3 long vowels, them being a e u, and the long version of each. so in the same way a child would learn the pronounciatin of the letter rather than the name of the letter in school, you should do the same. so try
gha
ghe
ghu
ghaa
ghee
ghuu
there are a fair few rules in arabic, the good thing about the quran is that it is written with all the vowels and sukkuns present, whereas normal wrttn rbc s wtht vwls, dont know why they decided to do that.
once you have learned the alphabet try to read the book that wrote the book on arabic, the Quran of course.
you could also try blacking your self up and moving to cairo for 2 month, thats a good way to pick it up, if you speak english it will cost you more
