I have three questions and three sentences please answer all of them or
any if you know the answers.

1.) Sentence: "I think the motivated leaks
done by the ruling party
with/through the help of its
stooges in the channels, specially in English media to divert attention from other issues"
My question: Which preposition, with or through, would be
right to use in the sentence one ?
2.) "This whole allegation trading and
controversy
will/would come to
a halt when he would be sacked"
My question: Which verb, will or would, would be correct to use
in the sentence ? Also tell which preposition, a or no preposition, would
be correct to use in the sentence two ?
3.) Sentence: "I'm ready to wager
whenthe investigation reports
will/
would come
there would be no incriminating proof against him"
My question: Has the word when been used correctly in the
sentence ? And which verb, will or would, be correct to use in the
sentence three ?
Thanks for reading and answering long list of questions
