1) When placed, the Christmas tree has a '2013' banner across it (no idea why), but it still allows for the completion of the 'Festive Spirit (Build a Christmas tree 2012)' reward.

2) When the Christmas tree is placed you get 250 letters, so with that, yes you can collect 450 letters in 8 hours, but otherwise it's impossible without "purchasing" letters or refilling energy.  Some people give one letter and some two; I'm not sure what the drop rate is for two letters but if you start out an 8 hour interval with 25 energy and stay on top if it 100% I've estimated that you can probably only get as high as around 300 letters in 8 hours, which is quite a bit short of the 450.  That being said, even if you do only 200 per interval and get the 3 Snow Angels, you should still get enough to build the Haven before the event ends.

3) Don't know on this one; the OP above indicates that it'll be part of a separate event after the Haven event is finished, but I don't know if that's accurate...
