Yes and no. Mobi files (like eReader files) can have the metadata set a number of different ways (3 actually). Calibre supports reading all 3 for mobi but only supports setting one. If that section is not already present in the file it will not change the metadata because changing it would require rebuilding the entire file. It would basically have to run mobi2mobi (or in the case of 0.6.x, ebook-convert in.mobi .mobi)

No. you will have to run ebook-convert in.mobi .mobi yourself.

Not that I'm a where of. I don't do much with mobi though so maybe.

But I feel like there are lots of features or aspects of the program that the developer has put time and effort into but that I either don't fully understand or don't even know about, and wish I did so I could take advantage of them...
It's a valid criticism. I'm very guilty of not documenting anything I've worked on (the / path tag and field:false in the search are two major things that people don't know exist but keep asking for). The only part that gets documented even close to what it should is the command line interface.

If you transfer all items in a series to a PRS-505 or 700 it should create a collection with the books in the series order. If you do them individually it may or may not. Or is it when you transfer all of them it transfers in the order you select the books... I can't remember, it's been a bit since I touched the the 505 and 700 drivers and that was mainly just moving them to use the USBMS driver framework.
