For the line length, you could set the Emacs window to have the right
width.  But I've also seen mention of vvb.el which draws a vertical
bar.  Not sure if that is applicable.

Regarding indentation style, maybe C-x h C-M-\ is good enough?  You
can configure the indentation engine quite a bit in most modes.  For
C and similar, see the CC mode info file.

Alas, the Emacs indentation styles do not add or remove newlines, so
the hanging braces thing cannot be checked (if I assume correctly
what you mean).  You can configure CC mode to auto-insert newlines
when you hit `{', I think.

The GNU indent program can add or remove newlines.
