Grammar explanation
Time up to a point in the past
We use the past perfect simple (had + past participle) to talk about time up to a certain point in the past.
She'd published her first poem by the time she was eight.
We'd finished all the water before we were halfway up the mountain.
Had the parcel arrived when you called yesterday?
Past perfect for the earlier of two past actions
We can use the past perfect to show the order of two past events. The past perfect shows the earlier action and the past simple shows the later action.
When the police arrived, the thief had escaped.
It doesn't matter in which order we say the two events. The following sentence has the same meaning.
The thief had escaped when the police arrived.
Note that if there's only a single event, we don't use the past perfect, even if it happened a long time ago.
The Romans spoke Latin. (NOT
The Romans had spoken Latin.)
Past perfect after before
We can also use before + past perfect to show that an action was not done or was incomplete when the past simple action happened.
They left before I'd spoken to them.
Sadly, the author died before he'd finished the series.
Adverbs
We often use the adverbs already (= 'before the specified time'), still (= as previously), just (= 'a very short time before the specified time'), ever (= 'at any time before the specified time') or never (= 'at no time before the specified time') with the past perfect.
I called his office but he'd already left.
It still hadn't rained at the beginning of May.
I went to visit her when she'd just moved to Berlin.
It was the most beautiful photo I'd ever seen.
Had you ever visited London when you moved there?
I'd never met anyone from California before I met Jim.

Hello kingson,
Normally, we do not use modal verbs in both halves of a conditional sentence, but it is possible when we want to make the condition more tentative. In this case, the sense of 'If you would only give us...' is 'If you were willing to give us...'
You can see this used sometimes to add politeness:
'Would' is the past form (used to show an unreal or unlikely action or event) of 'will', but that does not mean it is not a modal verb. In this case, it is both.

Hello kingson,
Both sentences are possible. The verb form in the first clause is passive and the auxiliary verb is omitted, which means we do not know if it is a present simple passive or a past simple passive. That is why both will and would are possible:
The first sentences describes a likely or plausible condition and its result. The second sentence describes a condition which the speaker sees as unlikely or impossible.
Both will and would are modal verbs.
The difference between the sentences is one of plausibility or likelihood, not politeness.

Hello kingson,
Modal verbs are one kind of auxiliary verb, which is what I think you mean by 'ancilliary verb'. You can see a list of auxiliary verbs in English here:
https://en.wikipedia.org/wiki/Auxiliary_verb#List_of_auxiliaries_in_English
You can read about the three moods in English (indicative, subjunctive and imperative), as well about how modal verbs relate to the topic, here:

Hello kingson
The second one is not correct. The first is correct, but a little strange -- I would say 'if' instead of 'once'. With 'once', I would want to say 'Once you have it, you will start using it'.
All the best
