OK, Update :
So I had ordered a second Brake switch, that I intended to "play with" - by installing a weaker spring to get the brake lights to come on when they should. But it turns out the second "Standard" brand brake switch (same as first one I ordered) out of the box worked a LOT easier. I could depress the spring with my fingers with A LOT less effort than the original "Ford" switch that was in the truck, and first brake switch I ordered, that I could barley move at all.
So that - helped - with the brake light situation, BUT the VERY easy / touchy - very little effort needed to apply the brakes was STILL a SITUATION/PROBLEM that I was not happy/comfortable with.
So after lots of calling around and searching other forums, it led me to the only thing left - "THE BRAKE BOOSTER" being bad... I know what you think and that was my thought too, - when a booster would "Go Bad" you think you get a HARD - NO power assist brake pedal feel. BUT it turns out the Vacuum booster has some sort of internals that (the way I think of it as) a valve that doesn't seal properly allowing for TOO MUCH assist, giving me that that VERY Easy/touchy brake pedal feel...
So I had changed out the booster and NOW the brakes feel the way they should - strong solid feel during the full motion of pressing/applying the brakes - and SAFE ! And the Brake lights work perfectly now!
;D

As far as the extra vacuum canister, I found out that usually an extra canister is installed for other vacuum accessories, and as for the brakes if you have a HEAVY cam, which results in low engine vacuum - the canister makes up for the lack of vacuum to be constantly available for braking. In my case I doubt it's needed, but as mentioned earlier - "more is better" (in this case) it can only help/be safer - so I've decided to leave it in....
