how many cups of tea do I need to drink before the caffeine will be enough to keep me up late?

You dont feel the effects of caffeine immediately, so you will not normally notice it.
However, some people dont experience it at all.
One cup should be fine. But if you are one of those people, you might need a few. Just try drinking one when you are tired, but in ten minutes, if you still feel sleepy, drink another.
Edit: sorry, I misread your question. I thought you said coffee. I know tea has caffeine in it too, but not as much. So most people will get sleepy from warm drinks. If you are one of these people, the effect pretty much cancels out.
I would say drink coffee, but thats up to you.
