To trim or not to trim, that is the question.
I only trim dead leaves, some people trim to get light penetration, some people trim everything off the bottom(lollipopping), some people trim most everything. With that being said, feel free to trim but if you plan on doing a lot of it, spread it out over a few days so the plant has time to recuperate after each trimming.
And Pal is right, that is the quickest way to get 1000 answers. Everyone has a different style, I haven't seen any tremendous benefits on any specific style. If there were, everyone would be doing it the same way.
