There will inevitably be trolls, but I think many of the questions and mis-understandings originate from new ED backers/upgraders/purchasers, who just have the wrong expectations because of the confusion between KS rewards/pledges, backer upgrades, and store purchases.
There's a 'new members' guide already, which is a great way of proving FAQs, but at the moment it's somewhat buried here:
http://forums.frontier.co.uk/showthread.php?t=4009
I'm pretty sure they'll be many more questions when Beta1/Beta2/Gamma/Release players join in, and I think it would be good to have a dedicated sub-forum off the main
Elite Dangerous forum, and at the top of the list, so it's the first thing a new member sees.
Something like '
New ED Commanders - Help and FAQs'. Collect the questions typically asked into an FAQ, and create stickies for more detailed explanations. Allow one 'open' thread, as a catch-all, like in the DDF.
As for the trolls, maybe FD have an algorithm to spot trollish behaviour
