Adding Android Market to Galaxy Tab & arabic language

I just bought Samsung Galaxy Tab today and unfortunately it does include "Android Market": So I need a way to install "Android Market" to my device and MUST be working too, so that I can download its applications successfully. I prefer American and the latest version of "Android Market" I need someone to tell me in steps what to do in very CLEAR and COMPREHENDED way. By the way, I am new to android world. Again the "Android Market" must be US & latest version, installed successfuly, working 100% and I can download all kind of applications within Android Market. ******Also I need Arabic language to be displayed as connected letters in all andriod system not only in the browser WITH a native arabic keyboard. Thanks Adding Android Market to Galaxy Tab
