Is TRIM enabled on these new MacBooks?

I can't find anything that that definitively says yes or no.

TRIM is enabled by default at the OS level w/ Yosemite. The only time you'd worry about this is if you change the SSD, but with the new rMBs, that's physically impossible. So in simple terms, the answer to your question is "yes".

As above. If the machine ships with an ssd its enabled.

Apple will enable TRIM for its own drives by default and it has done this since the beginning of them using SSDs and the existence of TRIM. TRIM for non-Apple drives is something that isn't enabled but it doesn't need to either.
