This is my first contribution to this list, but felt that I had to put my 2cents in.
I have used Larson & Hostetler Calculus book for years and would not discard it despite the fact that it is missing those few topics (perhaps 1 weeks teaching out of the entire year). I have tried other texts and can find none that compares to the readability of this book. My students have continually complimented this text for the clear way in which concepts were explained. So I recommend that you hang on to it and use O&Z or the Harvard text as a supplement since both contain wonderful problems to challenge you students.
On the topic of Reform I offer the following thoughts:
Perhaps I'm old-fashioned, but I often wonder if my appreciation for some of the "new aproaches" to the topics of Calculus is a result of my knowing the material already. I say to myself, "that's an interesting way of presenting ...". But I'm not so sure that I would have the depth and breadth of understanding the concept if it was taught to me that way when I began to learn.
So, despite the call for change and reform, I probably will move cautiously and undoubtedly continue many traditional approaches with my BC students, since I am confident that they will gain understanding and insight the "old" way. This does not mean that technology will not play a role in my teaching and guided explorations. Of course it will be a component of the course, but not the cornerstone. And Yes: I will teach the MVT and prove The First Fund Theorem!!! I certainly think it more important than Slope-fields or Euler's Method.
Sorry to have gone on for so long... Alaine
