Answer 1

EDIT 2
This was fixed in this GitHub commit, which has been included in the newest version (v4.26) of gsutil.
EDIT
It looks like you actually uncovered a bug that occurs when using the XML API. I've opened a GitHub issue an will work on fixing this ASAP:

Thanks for the report!
Looking at the code in the Boto library, you're probably trying to specify SetStorageClass a JSON key:
{
...
"SetStorageClass": ...
...
}
rather than making it the value of the action's type attribute. Here's an example using your (fixed) sample from a question comment:
{
"lifecycle": {
"rule": [
{
"action": {
"type": "SetStorageClass",
"storageClass": "NEARLINE"
},
"condition": {
"age":30,
"matchesStorageClass": ["STANDARD", "DURABLE_REDUCED_AVAILABILITY"]
}
}
]
}
}
