It seems from your maps that the whole of the Canadian western coast and southern Alaskan coast inland as far as Alberta is effected. Do the stats bear out this, or is it just on the coast?
All the info I have comes from sources of those charts so follow those links for more detailed info, but my understanding is that these maps were compiled from historic data so the stats should bear out what's in the maps because the maps were drawn from the stats... if you see what I mean. There is obviously some variation from year to year though, so the maps represent the "average" effect of El Nino / La Nina.

I see you have a "colder" area further east, how many degrees does this change during this period?
I don't recall seeing a number anywhere, but my analysis of Whistler temperatures (see post #2 here) suggests that it's about 1C per unit of MEI. So last year, when La Nina approached an MEI of -2, I'd have expected Whistler to be about 2C colder than usual. Not much, but it can mean snow in the village rather than rain... In a strong El Nino with an MEI of +2 it'd be 2C warmer, on average.

Is the coast wetter section also colder?
Yes - where the blue overlaps the green it's both wetter and colder.

How much more wind dies there tend to be in these periods, and does the temp fluctuate more?
I haven't seen any discussion of wind speeds and I don't have any data on which to do any analysis, so I don't know. My analysis of Whistler did not show any evidence of increased (or decreased) temp fluctuations.
