If you've just received the kindle touch, give it sometime. Indexing is not limited to just your book, it also includes the dictionary, user guide, etc... A simple way to know whether it's still indexing the specific book is to do a search for the book, it'll tell you whether it's still indexing the book or not.
My KT was slow the first night as well(I put in just about 10 books), then I went to bed and the 2nd day it was fast. I do have the ghosting issue though
