I'm going over a few things,
For the first... All of your Disk image creators are bad except the Win32DiskImager.
Rufus, LinuxLiveUSB and Unetbootin are terrible because they overwrite your syslinux.cfg with their own. That can break the boot process.
There is an Icelandic VPN that is safe to use, the laws in Iceland do not require VPN services to keep logs.

This one does not keep logs as well as it isn't expensive..
GoogleDNS at least is probably one that you don't want to use. As Google keeps logs
https://developers.google.com/speed/public-dns/privacy
With Full disk encryption you should link this
https://wiki.archlinux.org/index.php/Disk_encryption
A lot of important information on there. As well as mention that you NEED to encrypt your swap. If say, you keep an application open in SWAP and shut down your computer by unplugging the cable, then data in swap is kept and can be seen. Thus; All type of information leaked, which is a breach into your privacy.
Overwriting data once with bunch of zeros is more than enough to make it unrecoverable. This has been proven as well as if you want to, I can find the research paper done on that subject. 3 times isn't really overdoing it but using something like the Gutmann method would be stupid. Yet even then, it is possible in theory to recover the data so you ain't perfectly safe until you have physically destroyed the hard drive.
I find it really amusing that you should mention Google as "not safe" search engine but yet you list their DNS as usable. heh. ;-)
If I see something more. I'll just let you know on IRC. I think I've covered what I saw when reading this now at 2am.
