I don't know about 1.0.x but for Joomla 1.5.x you should do this
Open this file:
libraries/joomla/html/pagination.php
and remove the words Start and End from these lines:
// Set the start and previous data objects
$data->start = new JPaginationObject(JText::_('Start'

);
$data->previous = new JPaginationObject(JText::_('Prev'

);
and these
// Set the next and end data objects
$data->next = new JPaginationObject(JText::_('Next'

);
$data->end = new JPaginationObject(JText::_('End'

);
Then remove the extra < and > by deleting < (which goes for <

and > (which goes for > )from these lines:
// Initialize variables
$html = null;
// Reverse output rendering for right-to-left display
$html .= '<< ';
$html .= $list['start']['data'];
$html .= ' < ';
$html .= $list['previous']['data'];
foreach( $list['pages'] as $page ) {
$html .= ' '.$page['data'];
}
$html .= ' '. $list['next']['data'];
$html .= ' >';
$html .= ' '. $list['end']['data'];
$html .= ' >>';
REMEMBER NOT TO DELETE THE SINGLE QUOTES ( ' ' )
