I like your list, many skills there that I actually missed.
Adding a rather not-sop-exciting - but still useful both in a sims make-money-spend-money universe as well as in RL: Economics. I'm often looking for a sensible skill for those of my sims who want to make a good home budget or perhaps just get a job as an accountant etc. There could be animations like comparing values or usage of items, or "discuss values" communications. High skill could even affect bills because someone with high economics skills would make a good budget to save money. Yupp, I know it sounds boring, but I think quite a few of my sims would build such a skill.
Also miss Cleaning skill (we had it in TS3).
Oups: Just noticed this thread is quite old, LOL.
