Your trunk damage could be rabbit or vole also.  I've had good luck 
w/ the plastic spiral tree wraps, but I know that others on this 
group have not.  Its just damage that will have to heal.

You might want to prune the terminal buds, but it depends in part on 
what training "Style" you're looking for:

Vase (usually used for stone fruit, but sometimes pome fruit):

Central Leader:

(one thing I noticed about this that it does not mention:  On a 
typical "central leader" write-up it says that "each" scaffold branch 
should be seperated from another on the trunk by 5-6 inches.  Hmmm.

Modified Central Leader:
Basically Central Leader that you only let get so tall and 
then "prune to a weakly growing branch".  I'm going to be using this 
alot.

French Axe (I believe Ed Fackler used this system extensively):

Probably the lower buds should be removed.  On some varieties of 
grapes you might want to leave a few lower buds as an "insurance 
policy" for winter kill, but Canadice is fairly hardy.  Do you have 
your trellis up?  Do you plan to use cane or spur training for your 
Canadice?
