This should get you what you want (I hope you understand a bit about html):
Text Formatted Code
<div id="text_editor" style="display: {show_texteditor};">
<dt><label for="introtext">{lang_story}</label></dt>
<dd>
<textarea cols="45" rows="15" name="introtext" id="introtext" class="wide">{story_introtext}</textarea>
</dd>
</div>
<div id="html_editor" style="display: {show_htmleditor};">
<dt><label for="fckeditor_toolbar_selector">{$LANG24[70]}</label></dt>
<dd><select id="fckeditor_toolbar_selector" name="fckeditor_toolbar_selector" onchange="changeToolbar(this.value);">
<option value="editor-toolbar1">{$LANG24[71]}</option>
<option value="editor-toolbar2" selected="selected">{$LANG24[72]}</option>
<option value="editor-toolbar3">{$LANG24[73]}</option>
<option value="Default">{$LANG24[75]}</option>
</select></dd>
<dt><label for="introtext">{lang_story}</label></dt>
<dd>
<textarea cols="45" rows="15" name="introhtml" id="introhtml" class="wide">{story_introtext}</textarea>
</dd>
</div>
I took part of this code from the Admin story editor.
Add it to the template file in your theme under /submit/submitstory_advanced.thtml
under the topic selection and remove the old story label and textarea code.
This will add in the toolbar. I added some language variables to the labels since the template variables are not filled in by Geeklog (would require modifying of core).
You can also change the selected="selected" part to what option you want to be selected first.
I tested this and it all worked well.
