Have faith, the entrelac thing will work. It's one of those projects that can look like garbage on the needles, but improves immensely when you block it.
Knitting backwards is pretty essential for entrelac, for exactly the reason you mention - turning the work every few stitches makes you crazy. I don't know of any online resources for it, though I'm sure they're out there.
What Bea and I did was just take it slowly. We worked on it together, visualizing where the needle had to go to form the stitch. It wasn't hard, really.
Since "knitting backward" is just another way of purling, but from the knit side of the stockinette, all you have to do is place the tip of your left hand needle into the back leg of the stitch on the right. Wrap your yarn as usual, and pull the stitch through.
It can be helpful as you begin practicing this to put the needle in place and turn the work around, so you can see that it's really placed as if you were purling on the reverse.
As with anything, it takes time and practice. I've done enough entrelac that the backwards knitting comes pretty naturally to me now, and I'm almost as fast in reverse as I am going forward.
I hope that helps! I'm not sure how good at explaining it I am.
I wouldn't worry too much--I just got my Interweave yesterday or the day before.
I'm almost finished New Moon and I'm really looking forward to Breaking Dawn. I really like her style so I will probably like whatever she does with the characters.
Did you hear they are postponing the next Harry Potter movie??? Till NEXT SUMMER because it's "more profitable."
