If you're looking for a Mk7 (i.e not a 7.5) then cars built from week 22 (end of May) 2015 should have the winter pack fitted as standard, along with MIB2 sat nav and keyless entry.
Climate Screen is quite a rare option on the Mk7 as it was bundled in with the advanced phone prep which made it expensive. On the Mk7.5 it was available as a standalone option for £300 which is a bit more palatable.
I have the climate screen on mine. It was great in the recent icy weather, but I could probably manage without it if needs must. There are around 8 or 9 months a year when it doesn't get used. Putting the blowers on full for a minute or two does a pretty good job of clearing any mist on the inside.
