Answer to Question 1

Glucose and amino acids (obtained in proteins)

Answer to Question 2

Because of competition among all the amino acids contained in proteins for the active transport systems that allow penetration of the amino acids into the brain, it is unlikely that adding tryptophan will have much influence of serotonin levels in the brain.
