Having finished the crypt, toadem and serpent castle should I keep items (i.e. bauble stick, serpants wand)in my inventory which were used for specific purposes in these earlier sections. Will they be useful later in the game or are they just taking up space in my inventory?

regarding BOOKs of magic, if i already have the spell should i then sell the books in town as they will be of no further benefit to my party?

Once you're sure that the item is no longer needed for its particular quest you can drop it. Note: Did you plan on trading the serpent's wand for Harespia's orb (a magic shoppe quest)?

And you can sell the books, too. Though you may want to hold on to the tomes of the elements if you plan to ascend a character to Zenmaster later in the game.
