So far as the frame rate goes, the best way to look at is this. Cinema standard (24fps) is sufficient, -IF- you are willing to adopt the limitations of the format. Movie film works at such a framerate due to the fact that with film, you get motion blur as an intrinsic part of the media. If your render has motion blurring done in it at rendertime, you should be okay.

But.

Without that very expensive ( rendering timewise) motion blurring, 24 fps is right on the edge of detectable flicker issues. People with sensitive eyes could detect the frame flicker, and depending on color pallette, scene lighting, and camera positioning, you could have a video that generates too much eyestrain to be enjoyable. 30fps is better for computer viewing, as it is above the flicker threshold (at least for 98% of the population. A few people are able to detect it).
