Also it could allow brake fluid to enter vacuum lines which would cause the smoke/ stumbling I've been getting?
Not so sure about the brake fluid entering the vac lines...
Is the Master cylinder leaking, as in there is brake fluid at the rear of the master cylinder running down the brake booster?
And ys if the brak booster is bad enough it can cause a sorts of issues...
As a test you could pull the Vac line to the booster and plug it and see if the issues go away... If they do the booster is bad... Be careful tho, there is really good suction there... lol
