I believe that you can use only the work[s] you're writing about and make a decent grade, but the guide does suggest that using other primary and secondary sources, where appropriate, can enhance the quality of the EE. You're doing Shakespeare, right? If you say that he says __________, then it might be useful to find something else he's written that supports this idea [which I think you're already doing?]. If you find someone who has studied Shakespeare and said that the playwright did not mean to say _____ at all but rather he didn't mean anything of it, then you can argue/defend your point further by addressing recurring motifs or something. Overall, primary has more value than secondary, as you probably know. I wouldn't spend too much time searching for secondary. =)
