If you completely change your site as you are planning to do, then you WILL get de-indexed.
But you can use 301s to redirect certain urls, but if you have too many products that can get difficult and not really necessary, as once you resubmit ur sitemap and your urls have proper 301's (atleast your homepage) it will take time but you can expect to get re-indexed.
Home page redirect is important as well as keeping the same content on meta info on the new pages.
With such a drastic content change you are definitely looking at some trouble from SE's if not done properly.
