Photoshop Elements help

[Mitch1640]

I recently got PS elements 6 and i was using picasa for tuning up my photos a bit. I really liked their graduated tint tool but i haven't been able to get it to look as good in photoshop can someone please help me? Also is there a way to edit the tint without having to undo it then going to the gradient menu, adjusting things then redoing it?
