Should the filter paper and the wooden stick be sterile?

No, they don't need to be sterile since you will throw both of them away after the test is done. However, if you touch a colony on the plate with a non-sterile stick, that colony is contaminated and therefore shouldn't be used for anything requiring sterility, e.g., subculturing for isolation. To avoid this, you can use your sterilized loop to pick up a colony and transfer it to the filter paper for testing.
