I personally brought around 4-5 prayer pots and a holy wrench and ran around with Protect from Melee on. Bring some food though for the handholds. You still last for quite a while. I would wear full initiates, guthix book (or any completed book), holy symbol, and dragon mace. But keep in mind, you'll have to make room for unequipping the book, weapon and amulet when entering the mourner's house.
