I use "eBook Tidy", which has a "change single quote to double quote" function. This function changes what the program percieves as being quotes and does a pretty good job of leaving apostrophes alone. The only problem with ebook tidy is that it only handles text. Pictures get wiped out of the material as soon as it is imported. Works great for novels and text only books though. I'm pretty sure if you Google ebook tidy it leads you to the download page.
