The only small piece of concrete advice I have for you is to do with online security. My 90-year-old mum was using a single password for all services, and had started to use it for places that allowed you to purchase things, like Amazon and PayPal. I added her to my 1Password account and helped her change all her passwords to 32-character mixes of letter, numbers and symbols, then taught her how to use it. All of her password are stored in a vault that is shared with me, so if she needs to set up an account on a new site, I can do that for her and add the item to 1Password so she can use it straight away. I always had this nagging feeling about her using the same password, and I'll happily trade the occasional 1Password support phone call for the peace of mind I get knowing she's not using the same password everywhere.
