How Big Should My Comp Be When Working With Cameras

Hi everyone,
I'm new to the community and am totally amazed by how helpful everyone is here.
I am hoping to get some advice with a project I am working on. I am working with 2d objects and I have turned them in to 3d layers using the 3d switch. Some of the objects I am working with have been created in Adobe Illustrator and some in photoshop. I plan on zooming around in the comp using cameras, and doing several close-ups on 2d objects. I would eventually like the finished product to be exported to 720p. My question is how big does my comp have to be in order so that when I zoom in with the camera, the objects don't look pixelated?

Use a 720p preset for the comp.
It's not the comp size, it's the apparent layer size.
If the layer appears bigger than its original size (1:1), it will pixellate. If you enlarge it by scaling it up or by zooming in on it, it will pixellate if you go far enough.
For example: In a 720p comp, a 640x360 layer can only fill a quarter of the screen before you risk pixellation. In practice, you can make it look maybe 120% larger before you start to see pixellation. If you view the layer at a very oblique angle, the portions of the image that appear much bigger than original size will pixellate.
To see how this works, you may want to drag a copy of the source into the comp and leave it at 2D for comparison. Then you can see how much its 3D version (apparently) enlarges when you zoom in on it.
So to recap: it doesn't matter if you zoom in or scale up a layer. If you make it *appear* much bigger than 1:1, it will pixellate.
By the way, for Illustrator layers, use the Continuous Rasterization switch. Check the Help.
