In RB you can open the track in the audio edit window (Double click in the track), and then use the + - buttons to blow up the wave file till you can see the offending noise, and highlight and delete. Very easy. Also as Mac said sometimes the breath sound make the vocal sound real, or natural. So lower the volume on that sound. Highlight that portion, right click and choose audio effects, then gain change, and chose constant gain, in the drop down click on cut-3 db or cut -6 db or customize to what you want, if not right undo and start over.
