ooilingfan,
I think you are referring to the book "Minna no Nihongo". Well, many schools use that book, and I found that most Japanese Language Courses in Malaysian universities use that book.
Don't forget the JFKL (related with the organizer of JLPT test), Mid-Valley there are many books and references. Kinokuniya Bookstore in KLCC as well, they are selling many high standard books. Just have a look there. It is deep inside that bookstore, at level 4.
There is one Japanese language school in Japan, Meguro Language Center, offering really good materials, free on the website. Try search for that.
There are many China's website/forum on Japanese Language as well, they are free also, with the materials, good for listening.
If you like to opt for listening, then you might want to try the NHK radio. In fact, in the MLC website, they are giving quite a number of references for Japanese Language Learning.
Keep up your good work! Good luck!
