every area is different and some have more awareness than others. You already have a dx so I would ring them yourself and ask them what they offer in the way of behaviour management, what they can do for anxiety and stimming,
SALT can advise the school on social skills work as in small group work, games that involve sharing with a TA and one other child etc
Has your child seen an OT? for a sensory profile? as it may be that he has some sensory issues that are making him act someways.
camhs are able to refer you to these people (at least mine are) but so can school call one in and so can pead refer you :)
To be honest I have learnt more from scanning the threads on here in what to ask for and how to try and help some ASD issues than anywhere else so why not plan a strategy list in order of priority.
eg: secure home: One thing I have found with my DS is no matter how much I talk about not doing or not touching he is totally compelled to do the same things again and again due to sensory reasons (as well as just plain stubborn!) So to get rid of wondering where he is or what he is up to or what he can reach I did a house sweep.
outside lock at top of bathroom door or security taps
in my case its keep shampoos, lotions, cleaning sprays, hairsprays etc well locked up as DS has an issue of just watching them poor away or sprays windows to watch them slide down. Door keys up high away from reach incase he decided to do a runner, window locks locked on vent as when he was small he had a habbit of climbing out and sitting on the sill!
Playing on his own:
Arrange a regular play date either with a friend or a child from family? basically not just you but someone outside of the house even if its an adult, to play turn taking, role playing, baking cakes together, team play decorating a box. All this is hard going as you have to be there all the time and cant relax and let them play on their own as its the social side you want to help him with.
Obsessions:
I have REAL problems with DS obsessions some have been fine in the public eye but he has a gun/lightsaber etc issue at present and as boys like guns in RL its a hard one to break as most kids he meets talks of heros! But what I do is limit him by using the clock. If DS plays a different game, or talks a different subject with me for a period of time then he is allowed X number of mins to talk on his subject or play his game. This was hard at first but I had to stick it out.
Clock: Try using the clock for pointing out how long till bed, how long sibling is watching programme for till its his turn for the TV, how long he plays a game of his sisters choice before he has a choice, how long till dinner etc etc. It can help stop the stressys and the "are we there yet" etc :)
Just some ideas which may or may not work and what I am STILL doing!
