I can't really help you - But I only had one female also in my tribe and she is a "runner" !!

Ohhh how I hated to "get her with child" and NOT be productive at all!!

I just LOVE runners - they get twice as much done as normal villagers! So it really upset me that I had to have her just sit around for AGES LOL

Collections = as far as I know - The First time you find a collectable it will show in your inventory - after that it just goes toward Tech Points. Someone correct me if I am wrong.
