for completeness, you need wpasupplicant as well for the 3rd stanza
of /etc/network/interfaces to work (and you want crda (>= wheezy) to
access channel 11-13/ most of the 5 GHz band):
# apt-get install iw iproute wpasupplicant crda

Small syntax fix

This should read
wpa-driver nl80211
the only valid choices here are:
- nl80211 all modern mac80211 based drivers.
- wext legacy and staging drivers - don't use, unless you have to.
it's preferred to just leave out wpa-driver over hardcoding
it to wext, because staging drivers will switch to nl80211,
once they leave staging.
- wired only for encrypted wired ethernet, basically not used
in practice.
Setting wpa-driver explicitly is no longer necessary since
wpasupplicant 0.7.x (>= wheezy), it will default to nl80211 and fall
back to wext as needed). However it was needed for wpasupplicant
<=0.6.x from squeeze and earlier (well, at least lenny and squeeze).

While I have no personal experience with iwlagn/ iwlwifi, it might help
to load the module with "11n_disable=1", as there've been a couple of
problems with both the firmware and the kernel module in recent times.
