http://hakore.bot.nu/openkore/manual/ still has one of the old manuals up. Fairly outdated, but all of what you need is described there.
Those values you are pointing out are telling the bot to commands to put when he talks to the npc. And yes, you will need to add a lockmap since you will be changing maps, it needs to know what map to go back to.
"storageAuto_npc_steps c r1 n" is the most common one, unless you're going to places like comodo where they have extra dialogue, or maybe the new worlds

Is my block for storage. After setting this in your config, you need to edit your pickupitems.txt You can add common items to not pick up if you're not wanting to run to town that often, or leave it picking up everything so you can sell loot and make zeny (would also require you setting the options for sellAuto in your config). Then you need to sift through the items_Control.txt to make sure what you don't want sold is put into storage.
Few things to note: If you're switching equipment, make sure to list out those weapons/armor/accessories in your items_Control.txt so they won't be storaged. If you never change equipment, you don't have to list any, because Kore will always leave what you have on alone. If you won't to go back and overcharge your loot, make sure to change values in items_Control to store everything in storage.
