Any way to delete BLACK for a 2 color (but no black) job?

Question

Hi there,
I am working on a large 600+ page textbook in which I am using two spot colors (very dark navy and tan). There is not going to be any black at all in this book, but since I can't delete the black swatch in InDesign (CS3), all effects like drop shadows etc. default to black. I'm hoping that there might be some trick or work-around to get the black completely out of my file. Once I finish the sample chapter, we will be sending the files to a formatter to layout the remainder of the book based on my design and the likelihood of black working its way into the layout somewhere along the way is pretty high if the color is still physically present in the file. I'd like to avoid having to check on-screen separations for 600 odd pages to ensure there is no black present before going to press if at all possible!
I am very grateful in advance for any advice that you might have. Thank you!
Best,
Sherill

Thanks Sandee,
I suppose I might have to do that. Unfortunately though I do need to use the navy at least for the initial design so that I can get in-house approval. I don't think the editorial and marketing staff would be able to envision what the design would look like if the black were navy. :-)
Thanks for the suggestion! It might help when the book goes to formatting.
