Hi,
#0 standard / reverse / 2-way drury is not a convention I would recommend to someone considered N/B,
this holds also true for weak 3rd seat openings.
And given your questions, no offense intended, I would recommend, you forget for the time being,
the existence of those bids, but an explanation can be gind here

#1 if you happen to play it, than use it ..., i.e. bid 2C, you have invitational values.
The 2C bid showes a fit and inv.+ values, opener bids either game, makes a jump rebid
in 3 of the agreed major, or bids a new suit.
As opener you should ask yourself - Do you think slam is on, when partner denied an opening
hand? What cards do I need? With the given hand, give partner AK A, in suits of your choice,
do you think you can avoid loosing 2-tricks?
If you say, he could have a single / void oppossite your doubleton, and if you believe this is
a realistical scenario, ask yourself the next question, have you the means to find out, that
partner happens to have such a magic hand.
Only if you believe, that it is realistic, and if you happen to have the tools available, march
on, otherwise sign of in game.
#2 2-way drury allowes you to differentiate between 3 and 4 card support.
Being a passed hand, you dont have much use for a 2C / 2D response to a 1 M opening bid,
hence the bid is idle. if you can remember the agreement, why not?
It is nice, if you have it, but you dont need it.
#3 After a intervention, I would not play it, but some say, if the intervention does not take
away room, why change the system.
With kind regards
Marlowe
PS: I dont play Drury, and I dont miss it.
