Thanks for the overview! I do similar backups in general, but with some differences in particular
1. Same. But I don't rate them, just choose what is worth to process and publish and put in subfolder.
2. I output only chosen content for publishing. The rest is left as CR2.
3. Upload to the web (site/blog/Facebook) downsized jpegs, but not a 100% quality. I have tested different settings and found that there is no really visible difference between 100% and something between 96-97% but there is a big difference in file size, which is still important for web these days. So I use 97%.
4. I backup on 2,5" external drives. They are small and don't require separate power connector. I usually backup only CR2, as I don't see notable profits from saving additional formats while much more space is required for that. It is always obtainable from the original CR2s. And it will be even exactly the same, because I do save Lightroom's XMP files from processing. In some cases, if I did a complicated PP in Photoshop – I do save a PSD files too. I don't use a fire safe. Will it really help in case of fire? I believe the fire won't enter, but I think disks will just melt inside (their plastic parts at least).
5. Well, shame on me, but I still did not settled offsite backup. I plan to do it in the nearest future. House of my mother-in-law will be used as a deposit box
6. Old hard drive in bank? An overkill level of redundancy for me
Some additional safety measures I use: I do not delete images from CF cards until I have a double backup on hard drives.
