Sounds like you did pretty good for your first time.  Experience is the only real teacher in life.

Don't worry about the yellow goo.  N-Oxide is just as potent as the white stuff.  It has a different character, and some people prefer it.  It is said that the high n-oxide content of chacruna is responsible for that admixture's "more uplifting" aspects compared to jurema in relation to ayahuasca.

Don't discard any yellow goo.  Just let it dry longer, and use it.  If it is too gooey to store properly, add some ethanol to dissolve it and then infuse some herbs like caapi leaves for a nice changa stash.
