Do a retreat with a good teacher.
EDIT: Explanation: Doing a retreat (several weeks of day-long practice with no other occupation) is much more beneficial than doing equivalent meditation time e.g. over one year, one hour a day (I read this somewhere written by Kenneth Folk, and my experience confirms that 100%).
Insights ("epiphanies" as you call those) occur naturally as your practice progresses, and emotional reaction sometimes occur as well. Intense practice helps you deal with both -- more insights coming, less attachment to them (you don't have to think about insight, you just need to be present, and let it come and go as anything else; it does the work by itself), and the emotions are dealt with within the practice, as another hindrance you get over by awareness of the present moment. That way, the emotion is cleared quickly (if you practice, have emotion, then don't practice for 1 day, the emotion9s) might go wild).
Retreats with regular (daily) individual interviews with a good teacher were very important for me, especially at the beginning, as things (emotions and insights) happening might be unusual and unsettling. The teacher can help you not get lost, not go too much into emotions, if possible, just note them and let them go.
Meditation, if done right, is the true teacher, and it also clears some of the bad motivation you may have for the practice (such as being great, or understanding everything, progressing fast, etc); that simply perishes under the scrutiny of mindfulness.
Since you ask about literature: I am not aware of traditional literature on this subject, which is due to my limited knowledge, and also the fact that vipassana was until recently (say 19th century Burma) practiced almost exclusively by monastics, if at all. From the contemporary writings, Daniel Ingram's Mastering the Core Teachings of the Buddha has a chapter "Practical Meditation Considerations" (section Daily life and retreats) which touches the subject; Kenneth Folk wrote on that as well (somewhere on the web, can't find it now).
