If you remove the bearings cages you need to add a few more bearings to make up for the empty space. Never had a Sugino bb so I don't know how many.
If you spin the cranks w/o the chain on and hear noise something is ****ed. My guess would be the shop put one or both cages in backwards. If a shop installed this take it back.
Try grabbing the crank arm in one hand and the frame in another. Try moving the crank arm in the direction the axle is pointed (not rotational). If there is any play the bb is loose.
