Hello Michalis. Those are pretty rare mats now. I have some of what you are looking for - with the exception of the Excellent corrupt skins (have not done a Pei-Ruz run in years).
I do not believe that you will be able to find the Q259 kinrey mats outside of Demon's Lap now since boss guards no longer drop mats.
Regarding the Choice Named - slightly easier but not much since the Jungle Q260's are squishy - spawn only after a server restart - spawn in a mob-infested area, die quickly and then need to wait for another restart, and be lucky.
Talk soon.
