You arn't making much sense. When I talk about the size of your imports, I'm talking about all your models and stuff you have "Imported" into your map.
So what do you mean by "23, 332"? Is that KB's of all your models?
Well there is no definition for "too big". If you want to play your map in multiplayer, the map must not be any larger than 8MB. Otherwise, it doesn't matter how big your map is. However, the bigger your map is, the longer it takes to download. Big downloads can get annoying.
