The idea is, to use an expression-mapping (:h map-expression) and
analyze what is one character before the quote. For example the first
mapping translates to:
:imap " Map in insert mode
<expr> " use an expression-mapping (that is, evaluate the right side of
" the mapping, instead of replacing literally
" " When a quote is typed replace by this expression:
getline('.')[col('.')-2] =~ '\S' ? ' »' : '« '
The right side uses the short form of an if-else statement <expr1> ?
<expr2> : <expr3> which is equivalent to if <expr1> is true, then <expr2>
else <expr3>.
This means, get the character before the quote. If this character
matches a non-space ('\S'), we assume the quotes come after a word has
ended, so you are ending the quote. Therefore we will replace the double
quote by ' »'. Else if the character before the quote does not match
non-whitespace, that means there is some whitespace in front of it and
we assume a new quotation will be started, so the double quote is
replace by '« '

You can possibly also do something like this:
nmap <silent> <F10> :s/\(['"]\)\(<C-R><C-W>\)\1/« \2 »/e<cr>
Which should take the word under the cursor and replace it by your the
guillemets, if it has a quotation around it. See :h c_<C-R><C-W>, to
insert the word under the cursor.
The 'e' flag to the :s command, prevents, that an error message is
given, when no match is found and the <silent> prevents, that the
mapping will be echoed in Vims commandline.
The same for visual mode can be expressed like this:
xmap <silent> <F10> :s/\(['"]\)\(\S\+\)\1/« \2 »/eg<cr>
where it will replace all non-whitespace enclosed quotes by the
guillemets, that are inside your visual selection (or more correct, that
are on the lines, defined by your visual selection. You could add the
'\%V' atom at the beginning and end of your pattern, to make sure to
only replace within the visual selected region, but unfortunately the
'\%V' atom has some bugs and doesn't always match correctly).

Hope this helps to understand what happens. If you have still problems,
please let us know.
