One thing that is a chore is remapping keys due to conflicts with mods. A mod that I have been using a lot lately, and is really helpful with modpacks with a lot of mods is the NotEnoughKeys mod and can be found here: http://www.minecraftforum.net/topic/2189371-
I think this mod would be a great addition to the pack, and the mod author gives full permissions to use in modpacks.
