Sorry I didn't read your post entirely:-)
I can say about the Warsaw, I think the Stockholm will be a bit similar.
All lines are on sale. CdG, CdG CdG, Tricot, RdC (few items), Peggy Mofit, JW, H+, Homme, Shirt, Play, JW Man, some items Homme Homme. More previous seasons than actual. Prices vary from -30 to -20% for past season items. (Past seasons mean mostly AW03 and SS03 the earliest).
There are few items for Japan, or Paris only. Like the multi-coloured stripes tshirt (can't remember the name, Udo something:-) Shoes are mostly Fred trainers, and few JW boots.
I think at the at of Fab. Guerrillas will probably have new stock for summer. It depends on each store to keep the winter clothes or not.
