I think you are allowed knitting needles in your luggage that goes into the plane hold (main luggage), but you are not allowed them in your hand luggage because they can be classed as dangerous. If you want to knit on the plane, I have used pens before. If you use some thin pens or pencils, that should work.

I believe so, just tell them that it is in there and what reasons it will be used for.
No, usually the checked weight is different from the weight of the hand luggage. Check with your airline
