1. You will have to attend in person at the Case Review on 11th January and seek to have it adjourned on that date if you want an adjournment. However, be aware that it is highly unlikely that an adjournment will be granted. Instead, you should inform the court that you are now representing yourself in person and will be seeking more time to comply with previous Directions given.
2. The primary function of a Review is to assess whether previous Directions in relation to Case Management and the progression of the case have been adhered to and what needs to be put in place to ensure the smooth progression of the case to hearing. The fact you are now representing yourself in person is a relevant factor and you should use this fact to seek more time to comply with previous Directions.
3. If you require further time to file further evidence in the way of Witness Statements, then you should seek additional time to get this evidence. You should inform the court of the difficulties you are having in getting this evidence and seek the longest length of time you can to get it.
4. Be aware that in accordance with Article 6 of the Human Rights Act and the European Convention on Human rights, it is imperative that there be a "fair Hearing". One of the requirements of a fair hearing is that all available evidence be present to ensure a fair hearing. So make the point that it is essential to a fair hearing that all your evidence be available to you.
