Hair type and/or suggestions?

I actually have two questions.(1) What would you say my hair type is? (Pardon my cheap camera.) Some of the curls are bigger than others, and some pieces are just wavy. It's very thick, dry, and prone to frizz and breakage. I also get the occasional gray strand that sticks straight up like an antenna. (2) Now that I'm starting to take better care of my hair, I wonder if I could or should grow the layers out a little bit. I've always dreamed of having hair long enough to wear up, but maybe that's not realistic for me, with my hair type + age + size. Any thoughts?Thanks in advance for any help.
