Is this likely a Sony firmware issue or an indication that the publisher didn't do a good job at making the "ePub" or what?
The on-Reader version of Adobe DE punts the technical problem of reading large files using limited memory by giving up (and giving that error) if any HTML file inside the EPUB book is larger than 300k. Publisher’s apparently didn’t get the memo, but Books on Board posted here that they’ve informed the publishers of the issue and they and are in the process of fixing the problem.

Yeah, the current version of Adobe DE doesn’t do justified text at all. But on narrow screens and using naive paragraph-formation algorithms you get better grayness with left-flush text anyway, so no big loss IMHO.

When I open them, I find NCX, OPF, HTM files and a couple of folders (one with images). So where's "the ePub"? What would I load to my Reader? Or are these the components of an ePub that would need to be put together?
As wallcraft describes, EPUB books are actually ZIP archives. Er, I imagine the person who made the RAR file “EPUB” books used a generic archiver and just accidentally used RAR instead of ZIP. If you convert it to a ZIP archive it should be “good enough” for Adobe DE.
