So so so so you need a couple of things to do:
*****Copy paste your native folder or else patches will screw your custom native******First! Locate the 3 armors (and helmet and boots) (heirloomed or not, that is as you which) in the item_kinds1 file in cRPG, the file is a fucking mess (yes a big fucking mess!) so use ctrl+f to search for the armor, copy the whole armor line, thats is until the numbers touch letters.
Second! Copy said files into your own item_kinds1 in your new native folder. Make you paste them before the item_end line, once you are done with this, you have to set the number that is on top of your item_kind file to 3 more than it already is (I think you start out at 601, so bump that to 610 (611 with the gauntlets)
Third! Locate the mesh of all armors (and helmet and boots) in the resources folder and their textures in the textures copy the mesh in your module resources folder and the texture in the textures.
Fourth! In the module.ini (the file with a small metal gear on it) copy those lines: load_mod_resource = tenka_armour_pack and load_mod_resource = narfs_transitional_armour_pack and copy them in your own module.ini file.
As for the swords, they are already in the game, but hidden, so you just have to download this
http://forums.taleworlds.com/index.php?topic=105928.0 , make sure ALL armor and helmet and boots and gauntlets and swords have the ''merchandise flag,, enable and set their avaibility to 100 (or more)
Final words: due to some stuff being weird in Warband you might have to do the whole proccess for the transitionnal armor since they are tied to the same meshes as teh gauntlets you want, simply dont add a merchandise flag and they wont appear.
