Kiln dried pine is fine for structural things like houses, shelves, things like that but not things that are designed to be chewed, it probably wouldn't hurt if your ham chewed a bit but ideally you wouldn't really want it to be chewing pine.
Cuprinol garden shades paint is fine as far as I know, it does have quite a strong smell for a while after painting though so I would air out anything you used it on for a few days before .putting it in the cage.
