I don't think any of your _specific_ regexps depend on the syntax.

But in general regexps can depend on the syntax table since we have
backlash constructs such as \w which matches characters with
word-constituent syntax, or \b which matches the beginning or end of a
word.

I'm not quite sure about what you intend to do.  But I'll recommend
the very handy tool `M-x re-builder' for crafting some suitable
regexps.

(modify-syntax-entry ...) is a function call, not a function.  You
can use something like:

    '((lambda () (modify-syntax-entry ?\" "w")))
