Why not just use the TSL Hak_Pad? It's a clean install by the best modding team in KotoR II TSL and you use giveitem hak_pad to give it to your character once in the game and that's it - then you just use it from your equipped item slot whenever you want something - levels, skills, credits, items, crystals, disguises, ect.
Found here:
First install this : TSL Hak Pad
Then install this : TSL Hak Pad Booster Pack
*You need to install both to get everything I mentioned above from the pad. - Install the first link first, then lastly the booster pack.
I use this all the time and it's WAY better than "typing" in give item or set ability all the time. Plus it offers more. You can even upgrade inside of it , set a disguise apperance, or give a party member a Jedi Class.
