I would go ahead and get a D-SLR, if you can afford it. It'll be fun and you'll feel like a photographer
And they have the manual controls which you'll want to experiment with soon, once you get the ball rolling.
Get the DSLR, start taking pictures. Nice sunset? Take pictures. Flowers blooming in your garden? Take pictures. Shoot everything. Experiment with lighting, angles, zoom, etc. Start in "full auto" mode and then try the different settings. See what difference the shutter speed and aperture make, and so on.
Today's cameras are so well behaved that they can take pretty darned good pictures
in spite of you, and then you'll quickly learn what works and what doesn't. What would otherwise have been a simple snapshot can turn into a portrait with judicious framing and a nice lens with shallow depth of field, and maybe a little fill flash.
Your experience, coupled with a good book on photography, will help jump-start you.
I'm biased a little bit toward snapping the heck out of everything because most of my learning happens at a summer camp I volunteer with, where the kids are running around and I don't generally have time to sit and think about how to prepare and compose a shot. So I've learned to think fast and try a bunch of different things. Memory cards are cheap.
