Great setup overall, nothing substantial needs to be added.
However, I would like to make some (optional) suggestions:
► If you like to test malware samples, I recommend you do so within a
virtual machine.
VirtualBox is a powerful, free and open-source virtual machine deployment and management application.
► KeePass is a great alternative password manager to
LastPass, with excellent and versatile
security features. In addition, it is open-source software, which means that anyone can check the source code for malicious functions, and thus, if they do not trust official builds, they can compile a build by themselves, thus maximizing the security potential of the software.
Other than that, you're good to go!
Thanks for sharing your config with us!
