Use a save editor like this one, you will be able to quickly level and get all the items at least. you will have to redo the breeding and dialog over again though.
It takes some fiddling to figure out wich items in the save doc, are the ones that actually effect your inventory. but as long as you use cntF to find item, it will be ez.
I believe its the second row of numbers labled Items or inventory. GL
