I would get a clarinet that you know plays - that way once you strip it down and replace all the corks, pads etc you'll know that if it doesnt play wel its because of how you have repaired it and not due to other factors - eg a leaking tone hole chimney or register key pip for example.
For other work such as removing and fitting springs you could just practice on a real junker that has a sheared tenon etc
If you can afford it I would also recommend you get Reg Thorpe's complete woodwind repair book.
