Need Help on Going Batty quest series

I need help on Batman's sidekicks I have: Stephanie Brown, Dick Grayson, Tim Drake, Jason Todd, and Damian Wayne. There is one more but I have no idea who it is.

I also need 2 more of Batman's equipment I have: The Batmobile, the Batplane, The bat signal, Batarangs, and the Bat suit. Again I need 2 more, I greatly appreciate your help.

Thank you!

The missing Robin is a red-headed girl.

For the equipment, think more vehicles.. one wheeled, and one aquatic.

@NWfanboy77: Did you get these?

I hope this isn't too much of a spoiler but maybe, for Robin, you should check out The Dark Knight Returns.
