Are the properties (bitrate, fps) of my h.264 video OK for the web?
Sure - it seems ok. However, it is also a good idea to offer other types of video for browsers that do not support mp4 / h264. The usual best practice involves supplying mp4, webm and ogg as containers. This site is a good reference.

A back of the napkin calculation:

1000 viewers / month @ 7.4 MB = 7.4 GB / Month.

Which is probably within the acceptable range for a generic server, just make sure the traffic allowed by your server provider can deal with it...

Assuming your server has a gigabit uplink (which is generally a bit more expensive), you could "theoretically" serve this video to 5000 users concurrently, however this won't work with normal apache servers - and it is probably a good idea to host the media files at amazon AWS (or whatever) if you are expecting that kind of traffic.
