To import items from other regions you need to do minor translations for the values. If you don't have a program that does this for you, you'll have to correct the records by hand. You have to be wary, there's at least 5 different versions of IFF files in use for each file, so you better know the structure.
For basic operation and use it's sufficient to have the item data in the IFF files, for a lot of other features you need to insert data into the database, though (and I'm not talking about Item_Typelist only!).
Simply put: This isn't something you do between getting up and showering, it takes some experience to do this correctly and you better have your own set of tools ready, otherwise it'll be a lot of manual work if you want the items to work correctly in all situations. Study the IFF files thread, compare KR and TH IFFs... you know... work with the files. No guide will replace good old-fashioned hands-on experience you get from experimenting on your own.
