hmmm, I don't know about a "beginners guide" but here are some tips.
Corals Highest lighting to lower lighting. Just my list from experience. I'm sure this topic will get a variety of opinions.
Clams (though there are diff types that need diff lighting) MH is best
SPS (these tend to be Acros and the like) MH or HO T5 though some are ok under less light if they are closer to the lights.
LPS (candy cane, frogspawn, hammer) These do well under most types of reef lighting.
Misc (Zoos/Zoas, shrooms...) Also do well under most reef lights.
Softies (xenia, leathers, colt coral) These require less lighting and have even been kept under strip florescents in some cases. (note I wouldn't try to though)
I know I am missing a bunch of types but I don't have my coral book with me for reference. If you are looking for a cool coral book there is one called "Aquarium Corals: Selection, Husbandry & Natural History" by Eric Borneman. I have found it quite interesting and useful.
