JenMorri88... I moved the one question Camille had moved, plus two more of your questions to their own thread. You will get better responses asking your questions directly, than to tag onto someone else's thread, unless your question is specifically related to the same type of orchid and/or problem with it.

First off... Welcome to Orchid Board! There are a lot of folks here who can help you in answering your questions. And sometimes we need to ask more questions before we can give a good answer to yours.
Phalaeonopsis (Phal for short) likes shade, as in no real direct sunlight on the leaves. So if it's in a south window and receiving direct sunlight you may want to move it back a bit.
Phals are notorious for aerial roots. Sometimes there's a reason (like poor potting medium) and sometimes they just do it and are fine.
Temperature range for Phals runs around 60F nighttime low, to 85F daytime high. Anywhere in there won't bother it, but they do like to be on the warmer side.
Could be numerous reasons for buds dropping: watering too little, sudden change in temperatures, getting a new one in bud and having them blast because you're now growing it in different conditions than it was in before.
Cracks in a cattleya... we'll probably need to look at a picture of it to know what you're talking about. Some folks can't post until they have five posts, so if you can't upload a photo, do two more short posts and you should be able to proceed.
