Hello!
1. How does a metapost figure (\startMPcode) becomes a node?
never, that is: it's turned into whatsit nodes with pdf operators and
mixed with regular nodes when text is used
2. When does it become a node?
sometime in the mp converter
3. What type of node it becomes?
whatsits mixed with regular (for text)
4. Can I change its attributes?
whatsits can of course have attributes but as the content is arbitrary
pdf these attributes don't play a role
5. Can I change its colors or transparency levels?
only by parsing the content or by hooking code into the converter or
(better and more robust) by just applying color or transparency at the
mp level
