there is an excellent textbook I would like to share with you, I like it because it uses simple vocabulary to teach you grammar, it is recommended especially for beginners http://www.kri.unsw.edu.au/Education.htm look down the page you'll find lessons and exercises in one pdf

you can check out the courses from the university of Washington https://catalyst.uw.edu/workspace/soohee/16500/94300

I still love the 서강 한국어 (Sogang Korean) series. I have been using it for more than a year now. There are two kinds, one purely in Korean and one for foreigners learning Korean so I think you should use the latter (though I have been using the one in Korean since my tutor provided me with that and it helped me a lot). Another good textbook in my opinion is the series from Seoul National University. In my opinion, any textbooks that are produced by universities in Korea are great resources in learning. ^^

저는 한국어 자습 교재로 국립국어원에서 발간한 '세종 한국어1,2,3' 과 서울대학교에서 발간한 'Active Korean 1,2,3'을 추천합니다. 클로에님이 추천하신 서강대학교에서 발간 '서강 한국어'도 매우 좋은 교재입니다. 그외에 재외동포를 위한 한글 학교용 교재도 있습니다만, 이와 같은 교재는 반드시 옆에서 누군가가 학생을 지도해 주어야만 합니다. 따라서 자습용으로는 적절하지 않습니다.

There are plenty of books teaching Korean. I am using Elementary Korean http://www.barnesandnoble.com/listing/2689904982872?r=1&cm_mmca2=pla&cm_mmc=GooglePLA-_-Book_45Up-_-Q000000633-_-2689904982872 It should come with an audio CD as well. I purchased mine from Amazon so it was without the audio CD so I can't give feedback on the book with the CD. However, I can tell you that it's really helpful since it teaches you think has both 한글 and romanizations and eases you into the Korean language. It also gives self tests and chapter reports. :)
