It's a (standard) POSIX shell. In general the commands are almost the
same as on your Linux desktop, so you can use the manual pages from the
desktop (or just google). For more information on the shell:
http://www.busybox.net/
The main difference from the desktop alternatives for the commands
which I've noticed myself is "find", it's lacking a lot of options
which the GNU version of find has.

Shorter than what is mentioned in the manual? Do you have some extra
software installed that could be consuming battery when it shouldn't?

Have you flashed the latest release? It has fixed some other video
issues besides performance.

It indexes the media files on your device. Media player shows only the
files that the crawler has indexed. Because the memory card is mounted
at boot (and crawler can't trust that the card contents haven't changed
in the meanwhile) crawler indexes that. There's a bug in the Maemo
bugzilla about its performance, you could add your vote for that.
If you notice that some particular media file types are particularly
slow to be indexed, please add a comment about that to the bug.
