I don't actually remember the way the cams are supposed to line up. That does look like it's off by a tooth, but the only real way to be sure is to count teeth on the timing belt between all the marks. I think the service manual has all the specs... Check out

I was missing that lower gasket on my car for a while too. At one point some shop must have lost it. When I noticed it was missing, I just uses some make-a-gasket to build up a rubber seal there. Note that I let it dry on the timing cover before installing it... so it wasn't actually glued down, it was just a means to cover the game like the original part. Later when I had the motor apart, I scraped off the gasket and bought one of the OEM parts.
