Not IcyTea, but I love answering questions so...
1. Westfire (F) Quailtuft (Any) Dawnwhisker (M) Wavefront (M) Flintsong (M) Hawkfeather (F) Stormfall (F) (name (gender you need to be if you wanna be mates with them) format)
2. Not yet
3. Good question, I can simply think apprentices weren't all that interested in joining a new Clan when Cedarhawk announced it at the gathering, where apprentices would be allowed to join in
