My 2 cents:
I read Dead Beat first. And I enjoyed the hell out of it. Of course, I didn't know what everything was, but it was still a fun read. This summer, I went back to read the series, starting with Storm Front and then going through the rest, in order (unless, I guess, you count the short stories, which were sort of in order for me, sort of not I guess, err... I don't know, whatever, they were fun.)
Did you have the same problem I did, and not realize the one you started with wasn't book 1?
I don't know why I have such trouble. I've got an entire bedroom dedicated for paperbacks and I still usually pick up a new series from the middle, even if the store happens to have the first one.
I missed it with tdf because Barnes & Noble didn't happen to have the first one. I had to hunt it down. They weren't even restocking it. At least Jim Butcher's books make it a bit clearer that book #3 is book #3 in the series.
(Simon R. Green, are you bloody listening? I hate having to open a book's cover to try to figure out if the author had other books in that series already.)
I often find myself picking up a new book and trying to figure out if the book is a sequel or not. Sometimes it's a sequel, but the publisher doesn't print any mention that any previous books exist because it was a different publisher.
I usually have to resort to looking the author up on amazon or google to figure it out.
Thanks to Jim Butcher for not doing these things. He's got his books set to be clear on this. I just went through them last week to reread the series, and was able to figure out which was book 1 without having to open the inside cover or go look it up.
Now if we could only get bookstores to bre more reliable on stocking books, and keeping them in sorted order.
