I like to use my toe to wiggle it. It shouldn't be "slack", as in floppy. But you should be able to wiggle it up and down. Remember, looser is better than tighter. As long as it isn't hitting the swingarm, you'll be okay.
As far as alignment, the marks on the swingarm mean nothing. I just adjusted mine and the marks are way off. I take a straight edge, about a foot long, and put it against the face of the sprocket extending towards the front of the bike. I want the right edge of the straightedge to be aligned with the inside edge of the left side of the chain. In otherwords, right where the sprocket would be if it extended that far. The straight edge is simply an extension of the sprocket, so line it up accordingly. Will the chain and wheel always be in alignment? Probably not, but if I had to choose one, I'd like it to be the chain.
