Regarding #2: The developer tools don't run unless they're opened, so that shouldn't affect any normal users.

Although every now and then a 'normal user' might get an unexpected surprise when they accidentally open them. Reminds me of this http://www.reddit.com/r/webdev/comments/1tkld5/my_facebook_s...

Yes. Bandwidth and additional HDD space are used. But web browsers data footprint is small. Installed FireFox consumes ~68.1MB of disk space. Which is microscopic in the days of TB Hard Drives.
