Removing background color
I am trying to animate growing vines while rotate around them in 3d. I am new to After Effects but usually pretty good at this stuff but Im stumped. I tried loading the image as a *.png theN removing the background color using the color key effect but there is always a halo of color around my design. Messing with the feather sliders etc..doesn’t give me the effect I want. Does the design have to be a vector design for this effect to work right?

Well if you import it as PNG ist the image already transparent? Why would you need to key it?
You could also try to leave it as a Photoshop document in a seperate layer, and import that. It will import all the PS layers as AE layers.

Where are you creating your vines? If you’ve used Photoshop then I suggest that once you’ve made your artwork, turn it into a selection and drag it to a new window with a fully transparent background, export this as a PNG and then you’ll preserve the transparency. It sounds like you’ve exported the PNG with a white background rather than a transparent one. What you need to remember as well is that your artwork will be pixelated in PS which may account for the halo effect. Check out Andrew Kramer’s tutorial on this very subject where he’ll show you how to do this in 3DS Max and After Effects.
If you’re not using a 3D programme to do this then you’ll find it extremely difficult, if not impossible, to pull the effect off properly since After Effects and Photoshop don’t have true 3D capabilities. Check out the tutorial on videocopilot.net and you’ll see what I mean.
Good luck!
