"Up, down, right, then left. It's not only the order for the switches nearby. It's the very order of the whole temple, so take note of it."
If one of them is lit and you have the boomerang, you can draw a path to make the boomerang hit both torches and light them both. Or maybe you have to hit a purple orb, make it green, and maybe that will light one torch. Then see above.
look behind the towers. there should be a gap. hit the two switches beyond the gap to shut off the torches.
first of all you can't buy the hourglass, but after you complete the first temple go to the "Temple of the Ocean King" can obtain it.
there is no bombachu bag in the temple.
I had the same problem. Pull the switches in the big room in that order. Later on in the temple, shoot arrows into the eyes in that order. Hope it helps, Archer5
