#2Well, if you're just after anonymous communication, use Tor over anonymously paid VPN.
If you're after real-life faked ID (as in real passport), you basically have to have relationships deep within the underworld and a lot of pocket money. Fake passports run between 5 and 10K EUR.

#3There are a few good articles on this topic online, one comes to mind which went all out, very good read: http://motherboard.vice.com/blog/how-aaron-brown-a-fake-pers...
All said and done though, if you just want to post / do stuff online I doubt you really want a fake identity, its an incredibly easy thing to screw up and there isn't much use for it. Just stay anonymous. When you think of them they sound the same, but put into practice they are very different beasts.
You need to ask, do I need an identity at all? Identity is something which can be known, validated or invalidated, most of the time, that is not what you want.
