I am exporting a 720p at 30 fps video from Final Cut Pro 6 using quicktime conversion. It has a field for data rate with no presets. What is a high mp4 quality data rate (in kbps) that isn't grainy?

"Isn't grainy" is a very subjective thing. Take a look at Wikipedia article about HD video. See that most online video services encode 720p at 2.5 - 4Mbit/s. Netflix encodes at 5Mbit/s. This is all using H.264 codec of course, which I presume you're using.
Depending on what the target for your video is, you might want to increase or decrease the bitrate. If it is to be watched online, probably smaller bitrate will do (you don't want your users to wait for long while the video is being downloaded), and if you're encoding your kid's first steps for your family video archive, you would probably want to go for a higher bitrate.
