Unlearn Traits?
You should be able to reset all traits for a fee at the trainer and have all the trait points available to use. It makes no sense to read the manuals again.
Manuals are a stepstone, needed just 1 time.

At level 80, it costs 3s50c to unlearn your traits. Just talk to your profession trainer and choose the dialogue option that says you want to change your traits.
You do NOT need to open their shop or to buy any manuals. As mentioned above, you only need to buy each manual once per character.
