If it had been growing outside it would have had better light and be better able to support itself, but putting a 'fence' of canes and twine around the bed is always a good idea..
Get it planted out as soon as possible - if it needs supporting individually use more canes and twine, but put the canes in as you plant so you can see what you're doing and don't damage the crowns.
Don't cut it back until the ferns have turned yellow and started to die back.
