Usage of speed brakes, v/s, etc.

I know I've made quiet a few threads lately, but im sure a lot of other newbies also gain from the advice of the more experienced on this forum.

I apologize nevertheless for asking too much, but again have some questions.
I was barely taught to use speed brakes, and v/s etc on TR, and now on line I see a lot of captains playing around with v/s which is very new to me.

I understand that you shouldn't or wouldn rather not use v/s to increase rate of descent that often, because it could increase speed a lot, but you would rather use speed brakes, correct?
If finding yourself below profile, use it to reduce rate of descent, and it will continue to maintain speed with no problems?

Can you use speed brakes and v/s both together?

ATC asked you to descent at 2500 ft per minute and maintain 250 knots.
What happens if you speed select 250 and put v/s 2500?
I assume the v/s is the priority and speed is disregarded? In this case do you use speed brakes to slow down?

Please feel free to add other examples, and any tricky stuff that you find ATC asking you to do, anything is useful.

Thanks in advance guys !
