OK, since no one has responded to my questions, I'm glad to say that I have solved those issues.
How to clear out the bullet and the arrow in tpl_site_map_default.php?
I know this is probably out from the original topic. But, if you have installed improved site map display mod, find this directory
\includes\templates\*yourtemplate*\templates
and look for tpl_site_map_default.php file. Scroll down to line 87 (mine), just clear out the arrow -->. That's for the arrow. As for the bullet, scroll up to line 51 and clear out this line
PHP Code:
<li class="first"><?php // echo BOX_HEADING_INFORMATION; ?>
That's all.
Now you won't see the bullet in Firefox and no space in IE anymore.

How to activate EZ pages to be listed?
Go to Admin -> Tools -> EZ-Pages. Then enable the sidebox for your page and don't forget the number for the sort order.
Hope this helps.
