1)How do you get the triforce and how much does it cost?
2)I'm having trouble trying to catch a bee. what's a good way to catch one?
3)Does a tarantula attack you if your carring the net, but run away if you are not? (dumb question i know)
4) About feng shi, I heard that it loses it's luck after a while. Is it true and if it is, is there a was to restore it without replacing a the feng shi items in my house?(like picking the item up and placing it back down?)

1) Buy it at Redd's, and IIRC it costs 12,000 Bells.
2) When you find the Beehive in the tree, go into a clear area, and equip your net. Then, you wait until the Bees move position to about in front of your face, then get out of the menu, and swing quickly. Hopefully you'll catch it.
3) I don't know where you got that from. I'm gonna say no.
4) See 3, but it's definately no.
