You want the fill functions. "C-h a fill" for more information. Some
interesting ones for you purposes would include fill-paragraph,
auto-fill-mode, and set-fill-column. There are plenty of other fill
related things you can set/use that you'll see whe you pull up the help
for them.

I haven't done any of this myself, but a quick browse through the xemacs
help system shows a bunch of coding-system related functions that look
like they'll let you set however you want the file to be encoded
(including EOL).

Beats me. (-= It's possibly a silly assuption, but it seems like
sgml-mode should have the appropriate things to deal with whitespace
correctly for it. You might have some luck looking up the mode's help
information (C-h m).

query-regex-replace would be what I'd use, but I tend to do strange things

You can enter any key you would like (even if it's bound to something) by
using the quoted-insert command. This is generally bound to C-q by
default, so try C-q C-m to enter one.
