Before you begin painting on a model, consider the type of texture map you want to paint (diffuse/color, bump, gloss, reflection), the resolution/size of the image you want to produce, and finally the bit depth for the image.
The paint criteria generally depend on your rendering software, or your production workflow requirements.
