Bee and wbtravis -
I'm right there with ya! I've been day (photo) hiking in the Sierras for years and just started backpacking last year at 44. I've been asked about hiking Whitney many times via the trail and MR. No thank you right now! It is on my list of things that I want to do, but only when I'm good and ready.
I have learned about the proper equipment from people this board and friends like Laura. I know I have the right gear...probably more than I need ;), but lack the skills to use it properly.
A good education, training, and lots of practice are the things that will get me up to the summit safely. In fact, I just sent an email to SMI last night to sign up for their snow travel course...you gotta start somewhere, it might as well be here and now!
