I don't know if this is now a closed topic. But as already advised you need to pull out of all reports whatever you see as identified needs or difficulties to go into section 2 of the statement. If you feel they have not even identified certain needs you can write to the professional responsible and tell them you are concerned he has this need that has not been identified.
Section 3 of the Statement should contain provision to meet each and every need.
Get yourself a copy of the SEN Code of Practice, if you don't have it already and go to section 8.
Any support he had previously can only be removed if a professional has produced an up to date report that recommends support is reduced or removed. Otherwise it is illegal to just remove it.
You should make sure you put in an appeal to SEND if you are not happy with the final Statement and the LEA are refusing to make the changes you are asking for (which must be from evidence you have in writing in reports etc).
Most LEAs just produce poor illegal Statements and hope the parents will be too intimidated to go to appeal.
But many LEAs do start to concede things as the appeal date gets closer.
For the appeal you can name the LEA and NHS SALT and EP and OT to come as witnesses to the appeal. That will allow you and the Panel to ask them questions about his support.
If you can afford it get independent reports and get those professionals to come as a witness (not a cheap option, but this is a major transfer to secondary school).
Are you happy with the school the LEA has named. Have you visited other LEA and independent school options?
All needs that affect education should be itemised in the Statement. And the legal interpretation of 'education' is very broad. So sensory issues will affect his ability to access learning in the classroom and therefore are educational needs etc.
