Are the prayers specific or you pray however you feel you should?
I wish I had time to answer better but in brief they are specific to what you are doing. So since we light candles it is the same prayer for lighting the candles on the Sabbath just with Hanukah substituted for Shabbat.
If you are interested in finding out in general terms about Judaism I would suggest reading a book called "The Nine Questions People Ask about Judaism" by Dennis Prager and Joseph Telushkin. There may be even a newer edition of it called the 10 questions
And btw I did not mean to imply you would not be a good doctor. I just wanted to impress upon folks my soapbox in regards to medical training these days
