^^^ Yes to all
You need to over outhaul it and then push CAREFULLY on the batten end in the luff panel to then use your other hand to force cams on. It is fiddly for experienced people and as Decrepit rightly says it is
not a beginner sail.
I am a bit

at the seller for seeing you coming. Sorry mate, he should be ashamed.
If you're in WA send me a message I will
give you free sails that suit a beginner to intermediate.
