You've got a good range/Mage/melee setup, so you're set there. However, for supplies I'd mainly just have prayer pots, maybe a few sharks, but rejuv/regenerate does most of the healing, as well as using Soulsplit and the EE seeing as it has a chance of healing when you hit.

 

Get a slayer helm & chaotic longsword/dual chaotic longswords and enhanced Excalibur. with abilities and EE along with the damage of chaotic you wont need much food. Not sure on current prices but you might even have enough to upgrade from bandos to torva, which would also speed up kills and lessen the need for food.

 

Any more help like spells I should use etc...
