Sounds like you have a good plan already to go.
Sort them into specific categories, put lists of needed work and names of who you have in mind for them.
Pick a simple one to finish so it isnt to intimidating and that will get you started.
When my DM left this world, I received all her belongings and did just that. What I didn't think was finishable with my skills I passed to others.
I finished special things I knew she wanted to go to certain people first then tackled everything else.
Have fun with this wonderful responsibility.
peace
