LA X 1 and 2 Questions

So I'm rewatching the episodes and I have so many more questions now after I've had the chance to digest everything.

1) Why did the van travel with them to 2004 (which I'm assuming it is because apparently it's when Desmond blew up the Swan Hatch)?

2) Why is Juliet at the bottom of a hole in the Swan Hatch? If in fact the hatch actually got built and blown up by Desmond, Juliet and the hole shouldn't even be there. Plus, when Desmond blew up the hatch, he was inside and even he got blown out of it.

3) Why is Rose reading a Weekly Woodsman on the plane? That seems out of place.

4) Why did Locke say he went on a walkabout, when he's clearly in a wheel chair? Is Locke now a liar?

5) We see that MIB/Flocke tore the piece of tapestry. Is this the same tapestry that we once saw in the cabin? What's so special about it and why did he take it?

6) Why did Ben lie to Richard saying the Jacob was ok?

7) Why does Jacob refer to the MIB as an old friend?

8) Why is the pen in Jack's jacket gone?

9) While Juliet is alive she clearly says it didn't work, then when dead she says it did work. What's up with that?

10) How does Jacob's body guards know about the ash, but doesn't know that the MIB turns into Smokie?

11) How is it that Ben can summon Smokie, but doesn't know about the MIB?

12) It seems to me that every number shown or mentioned in this episode is not one of the "numbers" I'm guessing that was done on purpose.

13) How could they not see the real temple behind the outside one?

14) If Cindy, Zach and Emma were all on flight 815, why didn't they time travel with the rest of our Losties? Looks like they've just been hanging out in the temple through all of this.

15) Why didn't Jack recognize Desmond on the plane, when they clearly met while running in the stadium?

16) When Myles listens to dead Juliet why does it sound like the Smoke Monster is coming?

17) Why does Jin get subtitles and the new Asian guy doesn't? I think that kind of sucks.

18) Who were the fireworks meant for? Richard?

19) Why is the MIB dissapointed in everyone?

20) Why don't we see Claire on the plane? Also, is Claire pregnant, cuz they never showed her belly in the cab.

21) Is Desmond married to Penny, cuz he IS wearing a wedding ring on the plane.

22) Why does Jacob die so easily and then disappear in the fire?
