Egede -- our situation and feelings were so, so similar to yours that I couldn't let that post go unanswered.
Don't assume there has to be a difference between future specialist and ASD 6-yr-old. He could well be both!
Don't stop expecting him to make friends. After a really rough start (undiagnosed) at school, my ASD son's leaving report from primary read 'He has a small but constant group of friends, and I have never known there to be a dispute between them.' Even though they have gone to (four!) different secondary schools, they are still very good friends -- unlike his younger brother, for whom friends seem to be just enemies-in-waiting (sigh).
Incidentally, his closest friends are all bright, slightly odd, techy-minded girls, who are a delight to have around. When your boy can find just one like-minded friend who isn't a pack animal, he'll be away.
Oh god, bloody eye-contact. My boy can't concentrate on instructions if he's looking at eyes. Teach him (if he's willing to play along) to look at their nose, eyebrow or chin instead. Takes away the anxiety for the child and fools the daft adult nicely.
Oh, and my son's current phrase:
Having Asperger's IS normal.
(are you in Cambridge BTW?)
