Is it possible to have it so that the plot marks would be filled and drawn, but the actual path wouldn't be drawn?
Here is example where it is otherwise the way I'd like, except those dots' should be filled with white:
\input tikz
\usetikzlibrary{shapes.geometric,plotmarks,scopes}
\tikzpicture[bend right, out=60, in=120, max distance=1.5cm]
\foreach \x in {1,...,8} {
\coordinate (n\x) at (\x,0);
}
\draw (n1) to (n3) to (n5) to (n7) to (n1);
\draw (n8) to (n6) to (n4) to (n2) to (n8);
\path plot[fill=white,draw=black,mark=*]
coordinates{(1,0) (2,0) (3,0) (4,0) (5,0) (6,0) (7,0) (8,0)};
\endtikzpicture

And here the dots are the way I would like, but the path is (of course) drawn:
\input tikz
\usetikzlibrary{shapes.geometric,plotmarks,scopes}
\tikzpicture[bend right, out=60, in=120, max distance=1.5cm]
\foreach \x in {1,...,8} {
\coordinate (n\x) at (\x,0);
}
\draw (n1) to (n3) to (n5) to (n7) to (n1);
\draw (n8) to (n6) to (n4) to (n2) to (n8);
\filldraw[fill=white,draw=black] plot[mark=*]
coordinates{(1,0) (2,0) (3,0) (4,0) (5,0) (6,0) (7,0) (8,0)};
\endtikzpicture

Is there a way to combine the two so that the dots look like in the latter, and the paths like in the former?

plotcommand intoforeach. This way you plot marks and declare coordinates at same time and can forget two last lines. Something like this worked for me:\foreach \x in {1,...,8} {\path plot[mark=*, mark options={fill=white}] coordinates{(\x,0)} coordinate (n\x); }– Ignasi Sep 6 '12 at 9:03
