So I know I'll eventually put coils on my G but I'm thinking for the time being I would do springs. What I was wondering is, my car has 61k miles, so would my suspension be too worn for springs?

 

Maybe not, go ahead and get the springs and install them. When you're having your alignment done have them check your suspension. A word of caution, stay away from the big company's like firestone/sears/pepboys and especially the stealership! Find an independent brake/alignment shop in your area, everyone has a good one.
