I get about 870 in TOEIC test. So I would recommend you some of useful materials such as: LONGMAN, BARRON, OXFORD ......
Remember practicing English everyday and listen to English music, news when you have free time.
You can download TOEIC Mastery and do the sample tests provided in it to check your listening and reading ability. I just do all the tests in it before I take the examination.
Try to get as high as possible in reading parts. It's quite easy and the questions are clear not vague. The questions are often linked to the text. So try to read carefully the content.
