They asked if I wanted to read the report before sending on to the school but I couldn't understand what benefit this would have, and it might slow things down so I said just send us both the report at the same time. (Did I miss something here?)
Reading it first just gives you chance to query anything and clarify before it goes to school.
But the things they're doing arent' really helping, and I don't think they're really providing him with enough appropriate support. They seem to have a bit of an attitude of - well we tried x & y, which is supposed to help - if it didn't help, then DS needs to try harder
That's a dreadful attitude, school telling him to try harder not to be disabled.
Hopefully they won't have that option when the report arrives.
Some schools are much better than others In some schools it's not worth fighting for what a child should have because school frankly don't want to be bothered and they never implement what a child needs, they only make excuses. If that's the case, seriously consider moving him elsewhere that has great SEN provision.
What can I expect the report to cover?
All areas he needs help with, assessment reports are pretty dismal reading as they are negative but they need to be like that so you can get the right sort of help.
It should detail all the tests they did and his scores. It's usual to find a spiky profile something like reading age 4 years above chronological age, reading comprehension 6 years below chronological age, that sort of thing. Some things he'll have scored well above average, some his scores will be within the ordinary parameters and some he'll have a definite deficit.
To have a dx of ASD, he'll have had to meet the criteria which is "The characteristics of autism vary from one person to another, but in order for a diagnosis to be made, a person will usually be assessed as having had persistent difficulties with social communication and social interaction and restricted and repetitive patterns of behaviours, activities or interests since early childhood, to the extent that these "limit and impair everyday functioning".

Whilst you're waiting, have a look at how to obtain an ECHP, plenty info on these boards if you search previous posts. If you start planning for that and getting it underway from when you receive the assessment report, you'll have a good idea of what support he needs for going into secondary school and which schools in your area may be a good choice for him.
