Which ones?  AUCTeX usually uses standard faces provided by font-lock
where available.

M-x customize-face RET ...

With GNU Emacs you can find out quite easily which faces are present
at a given position by calling `M-x describe-text-properties RET'.  A
less convenient method for XEmacs which seems to lack this function is
`M-: (text-properties-at (point)) RET'.

There is no distinction between LaTeX and non-LaTeX commands.  It's
more like between commands AUCTeX knows and those it doesn't know.
But this distinction is not consequently followed.  There are quite a
lot commands AUCTeX knows but which are colored with
`font-latex-sedate-face'.

With "commands" you are probably referring to the macro without its
arguments.  The "known" commands are fontified with
`font-lock-keyword-face' and the "unkown" ones with
`font-latex-sedate-face'.

See (info "(auctex)Font Locking"); <-- Type `C-x C-e' here.

One final word regarding font locking.  XEmacs is inferior to GNU
Emacs with respect to font locking.  That means some AUCTeX features
like raised/lowered display of superscript and subscript in
mathematical expressions or font locking of verbatim macros and
environments won't work in XEmacs.  If this is important to you, you
should use GNU Emacs instead.  A precompiled development version of
GNU Emacs for Windows which has AUCTeX already installed can be
obtained from <URL:ftp://alpha.gnu.org/gnu/auctex/>.

Compared to RefTeX AUCTeX has only limited support for citations.  So
you should activate RefTeX as explained in RefTeX's manual and plug it
into AUCTeX.  You basically add this to your ~/.xemacs/init.el:

(add-hook 'latex-mode-hook 'turn-on-reftex)
(add-hook 'LaTeX-mode-hook 'turn-on-reftex)
(setq reftex-plug-into-AUCTeX t)

And then you use `C-c [' for inserting citations.

RefTeX can find this out on itself.
