Spry menu bar woes (add submenu levels and edit width)

Question

So i need some spry menu bar help. Apparently as a graphic designer i'm also expected to webdesign, and while i can solve most problems with a good googling, i seem to be at  my wit's end fo this one.  So the site i'm doing has a header ith a horizontal spry pop-up menubar (in Dreamweaver CS4). But some problems arise:  when i manually add another submenu level, they don't show up in chrome or FF, they do werk perfectly in IE6. I just add the following code to the codepage:
<li><a href="#" class="MenuBarItemSubmenu">audio equipment</a>             <ul>               <li><a href="#">Digital Matrix Systems</a></li>               <ul>               <li><a href="#">R2 Digital Audio Matrix</a></li>               </ul>               <li><a href="#">pre-amplifiers &amp; mixers</a></li>               <ul>               <li><a href="#">PMX124</a></li>               </ul>
the PMX never pops open in FF an chrome.. Should i be adding anything else to another part of the code?  i'd like my submenu text to have a slight indent? How ever, when i add the indent to ul.menubarhorizontal ul , it elongates the submeny boxes in IE6, while looking normal (width) in chrome and FF. WHat part of the CSS style should i change to just have the text scoot over a bit without it really affecting the box layout? ALso, if anyone could tell me how to add a wee bit of spacing above the text (and beneath), i'd be eternally gratefull.  Also, how do i change the with of the submenus? seing as my main buttons are images, but the names i ned to put in my submenus are turning out to be pretty long...
HTML code for the menu:
