1. No.

2. Nope. See the What are Gems? short.

3. Ehh...my best guess is arbitrary convenience, as Bubble-Blitz said. Saliva to help with ingesting anything if they do decide to do that, or as an offshoot f corruption. Mucus: same reaosns humans have it: to hlep get id of anything stuck up their noses as evne though their made of light, I can imagine it'd be pretty irritating and distracting. I would also add that their gemstone probably only produces those things when they need them.
