If an item has a value of less than 50gp and it is reasonable to assume your character would have it you do not need to have it on your sheet. That is to say that it is reasonable to expect an adventurer to have some basic rope. It is not reasonable to expect a barbarian to have a quill, ink and parchment.
A caster is assumed to have any common spell components which cost no more than 50gp. If it costs more than 50gp I expect to see it on your sheet. The penalty for using a spell for which you do not have the components for after your first warning of said infringement will be severe.
