Interesting. As I have going to be working on Antarctic data, I guess I will be following your footsteps.
However, I strongly question whether your application should go the KML route which I think are heavyweight pains in the neck to use if you can avoid them. You state the reason for using vector is to be able to style and select. However, the better way to go is using WMS for visualisation and WFS for selection/query. Eg see http://openlayers.org/dev/examples/getfeature-wfs.html Also look at the SLDSelect example. You can pass styling to a WMS request as well. Compared to KML you will get faster load times (so you can have a significant no. of features in your baselayer); geoserver will do the projection into whatever polar system you use not JS; you can filter on attributes (eg 'STATION_VALUE>500') which you cant do effectively with KML (if this is important and feature no. is large, then use POSTGIS not shapefile); GML (what you get back from WFS queries) is faster and easier to deal with than all the KML varieties.
