Cleared to 14000 FT on climbout. ATC called vfr traffic at 14;500; 10 o'clock position. We responded 'not in sight'. ATC re-iterated 'maintain 14000'. Approaching 14000 FT received a tcas ta which quickly changed to a tcas 'descend now' as we leveled at 14000 FT. 'Descend now' changed to 'monitor vertical speed' which then changed to 'clear of conflict'. Lowest altitude during manuever was 13800 FT.
Leveled at 14;000 per ATL departure clearance. ATC gave us a traffic advisory for a VFR aircraft that was suppose to level at 14;500. While at 14;000; we both notice the VFR traffic came within +300 feet of our altitude. We then got a TCAS RA 'descend'. The Captain followed proper TCAS procedures and maneuvered our aircraft to 13;800. There was no further conflict and we reported TCAS descent to ATL departure control.
