Preparing a frame for powder coating

Hi,
Looking for some advice from those that have fully restored their Lambrettas.
Forks are out of my frame and I have took the fuel filler and dropped the bearing out. The question is do I need to knock out the bearing races before sending for blasting and powder coating. Also how is the chrome ring removed from the top of the fork tube I have removed the grub screw but it is not clear how the chrome ring comes out. Also planning on doing a repair on the stand holes before she goes for blasting. Has anyone welded stiffening plates in rather than leaving them loose?
Thank in advance
