Is this a new EHCP? If so, you could have threatened Judicial Review in order to get the draft and subsequently the finalised version quicker.
If it is an existing EHCP that has been amended unfortunately there isn't a legal timescale for sending the draft, but once they have sent the draft they must finalise within 8 weeks. Again, if this isn't stuck to you can begin Judicial Review proceedings.
Is this part of a phase transfer?
The LA must allow you 15 days to make representations. If they don't you can complain.
Are the reports specific and quantified? As the provision in section F is taken from the reports if the reports and vague and woolly the EHCP will be too.
The LA can consult whatever schools they like in additon to your preference, they don't just have to consult your preferred school. It is not unusual for the LA to consult more than one school. Is the school they consulted your nearest mainstream, even if the other is still in catchment? It doesn't sound like there has been a data breach.
"Up to 32 hours support a week" means nothing. Too vague and woolly. DS could end up with no support and you couldn't enforce provision. It doesn't specify 1:1 either.
At this point you don't need legal advice, unless you specifically want to, of course. Have you looked at IPSEA and SOSSEN?
