Adobe has created a .psd file that supports correct RTL Arabic. You can open this in Illustrator or Photoshop and you're ready to go. Works quick and easy and saves you shovling out loads of money on ME version.
I can teach you a small trick that I discovered myself;
Uing Microsoft word and adobe acrobat pro, you can type the text you want in arabic using the Arial font, then export the document to PDF format.
Now go to illustrator and open the file.
At first it will tell you that a font substitution will occur, then it will display your text in rectangles.
Just double click your text and select Arial font again and voila.......
just copy your text to your file and outline it.
