Ya'll
Here are a couple suggestions. First off you should really place mootools way at the beginning in your joomla template. Heck if your template has moo in it there is no need to add this line
<script type='text/javascript' src='{$mosConfig_live_site}/myscripts/mootools.js'></script>
You should also place the other files in the template too unless you are for sure you will not be loading them elsewhere. You will want to turn off JS add-ons if you are not using them. Only load JS that is needed. There has been known collisions with javascript of SOBI2 and other add on JS. (Not saying SOBI2 is bad or that add ons are bad).
Also if you are not seeing the slimbox appear it is probably not loading the CSS file so check that the CSS file path is correct.
Debug using firefox & fiebug. Do not try with IE.
However, you get things set in firefox then see if your site runs in IE 6/7. If IE gives fatal errors check these threads.
NOTE: These are not really Joomla 1.5 problems they are JS problems.

I just am not running gallery. They also are all playing nicely with SOBI2...
