Slower the better, in all circumstances??

Adding live rock on an on-going basis is not the best idea. Every time you add some, your tank may go through a small cycle as die-off occurs. Also, it may lead to algae issues. If you do decide to go with more rock, I would add dry rock instead to prevent any of these issues from occurring. Your live rock will seed the dry rock and worst thing that could happen is a small diatom bloom.

As for corals, definitely dive in. Leathers and zoas are easy keepers for the most part. If you decide to buy zoa frags, get ones with approx. 10 heads + on them. I find if you get 2-3 heads on a frag, it is harder to keep them alive.

I wouldn't worry about the lighting at all. Dip your corals in a coral dip solution to ensure no flat worms, etc. rinse in some display water and place them at the bottom of your tank to start as they don't require intense light at all.

Enjoy!! This part gets very exciting and very $$$.
