Any tips for learning Arabic?

I’ve always thought the Arabic language was really cool sounding and the script looks awesome, and knowing Arabic is a good way to make yourself marketable in the public and private sector.

This in mind, I recently picked up a stack of “teach yourself Arabic” books from my local used book store and started reading. It’s really not as hard as it seems and I’m doing rather well for not having a teacher, but I’m wondering if there are any resources out there that I can tap into to help me get at least a basic mastery of the language.

…And by resources, I mean websites, books you know of, audio programs (excluding Rosetta Stone), and just general tips from any of you who may know the language.

Thanks in advance and مع السلامة
