Besides self practicing in IELTS, you must do the following too:
i. Take Mock-Tests as many as possible.
ii. Practice Speaking with someone regularly.
iii. Focus all your practice on the 'Exam Format' as much as possible.
iv. Check your writing from someone who is good in English and can score you and also can suggest for improvement.
.....actually these are general guidelines; you may need individual advice from experts and that's always effective inshallah!

Dictionary - if you are comfortable with any good one - you may use it; Cambridge is surely good; I like Oxford much more; but, this is a personal opinion. Please use Cambridge.
