You can get kanohi masks in certain bionicle sets(eg. you can get the kanohi akaku from the toa kopaka set) or any way you know.
You can get many different colored masks in a mask pack (from 2001 or 2002), so you can maybe get a grey mask in it.

Find tutorials about modelling first. After learning about the modelling process use the techniques you have gained to make the Bionicle pieces and then you will have a Bionicle.
There currently is none.

We're sorry, but there is no way
We found something at The Bionicle Website and on Lego.com for download. That answers your question. Good luck.
There are really no more plans to make Bionicle anymore. Instead, they have released Hero Factory, which is similar to Bionicle.
