This seems to be a simple matter of choosing the right font.  IOW it
completely depends on your particular setup.  Maybe if you post
a snapshot showing the symbols chosen by Emacs for the actual characters
alongside the symbols displayed by X-Symbol for the corresponding TeX
commands, someone will be able to help you get Emacs to choose
better symbols.

That's just a conscious choice of the font-lock settings used in
tex-mode.el.  You could easily tweak those settings to additionally hide
the _ or ^ characters.

Indeed.  There's also no input method corresponding to the X-Symbol's
symbol menu, nor for its symbol table (which displays the symbols in
a buffer where you can select them wither with the mouse of by moving
the cursor to the symbol you like).
