In my experience, if you put mats into the crafting box that can make something, it will bring up the recipe even if you are not able to craft it. If you do try to craft something that you do not meet the requirements for, it gives a message in your chatbox in purple that tells you which skill is not high enough.
And as for being able to successfully craft items, whatever the minimum skill level to craft an item is +5 is about where you need to be to successfully craft the item on a regular basis. That was the rule I used in XI and it seems to be holding true here as well.
