Sorted and clarified!
An investigator can perform the Focus Action even if she has two Focus tokens. However, she will not gain additional Focus above two.
Likewise, an investigator can perform the Rest Action even if she has full Health and/or Sanity. She will not recover Health or Sanity above her maximum, but other effects will still trigger, such as removing Injury or Madness Condition.
Thanks for playing!
