I think if u(Gooner442) want to learn anything specifc, now it not the time to think of it.
Like u have said u have just started to learn maya.It is a vast package and becoming good on every aspect would be very hard.
I would rather advice u to focus on the current path rather trying to figure out wht u want to be.
Start with simple modeling..this is eventually lead u to texutring...a textured model will lead u to animation..which will force u to learn rigging...though this path, u will learn things like rendering etc etc stuffs.
I believe jumping to any specific part(like rigging, animating) will create big hole in ur maya-knowledge unknowingly.
When u will have enough knowledge to know which suits u best/which part makes u feel better..focus on that, on-that-time.
Till that time feel free to focus on whatever u want/like.Enjoy the essence of maya!!If u are a sceptical guy(like me ), then i can assure u spending some time with Maya wont dissapoint u!
