1-You will need to go to the port of entry (border) to complete the landing process, get COPR signed, passport stamped. You could land inside canada, but you need to call CIC to schedule for an officer to meet with you, which might take a while.
2-You actually need the passport, COPR and CSQ and $10.35 CAD. Also make sure your wife has a proof of adress (bills, lease etc...) or you could sign an affidavit attesting she leaves with you. Go to the montreal office, it is much faster, the whole process takes about 30mn (afternoons are less busy...trust me!).
Good Luck!
