what should be preferred: $x_1,\, x_2,\ldots,\, x_n$ or $x_1$, $x_2$, ..., $x_n$ I'm hesitating for the \ldots versus ...

$x_1$,~$x_2$, \dots,~$x_n$

is OK.

This is how Knuth use in TeXbook.

For me, I would replace the tildes with spaces.

I don't think one should use ... instead of \dots or \ldots.

it looks like in a normal sentence, ... should be used instead of \dots (at least in French as far as I know). When maths are involved, I am not sure – pluton May 22 '11 at 4:28
I know nothing about French typography. In modern fonts, there is a symbol and I think it should be used. (It is used when you use xunicode with XeLaTeX.) At least in TeX, \dots, and \dots. are widely used. – Leo Liu May 22 '11 at 4:31
