Hi Jae
Are you using Word 2002 or Word 2003? Are we talking about the Styles and
Formatting task pane (which you reach by doing Format > Styles and
Formatting)?
If so, then do two things.
1. Tools > Options > Edit. Un-tick "Keep track of formatting".
2. Format > Styles and Formatting. In the Show box at the bottom of the task
pane, choose Custom. In the Category box, choose All Styles. And now tick
and flick to choose the styles you would like to be displayed. Click OK and
your Styles and Formatting task pane will only show you the styles you chose
to view.
There's more information about controlling the Styles and Formatting task
pane at

And, before you give up on Word's built-in styles completely, you might like
