I think Lightfighter is THE place to look.

Add:

a Magellan GPS

GOOD gloves

Zip (wire) ties

Socks - Smartwool - I've personally found these to way outperform Thorlo's

Foam ear plugs to make sleeping easier...

Goldbond or baby powder

GOOD boots - Danner, Wellco, etc TRY THEM ON. I've had the same model and size fit slightly differently.

Sewing kit - make a good one yourself - an altoids size filled with "Craft and Button thread" and nylon upholstery thread can really help.
