Is it an Italian thread? If so, firstly check the drive side cup to see if it's worked loose.
As for the smoothness issue, I know it sounds daft, but are the bearing races in the correct way round? The side showing the face edge should be facing outwards meaning the side with the prominent bearings are on the inside!
I got my road frame second hand 4 or so years back, the bottom bracket was in an awful state and I couldn't work out why until I realised the bearings were installed the wrong way round. It was the same story for the headset!!
