I just came across this link on the Monachos.net website this morning: An Explanation of the Holy Week Services. A very good article. It includes the famous 1998 article of a Norwegian reporter, Niels Christian Hvidt, on the miracle of the Holy Fire. Check it out.
Update:
I also came across this meditation guide for each day of Holy Week (doc file) out of the Ukranian Orthodox Church Office of Religious Education.
