Hiya Jeff! Of course you're not too old to learn, plenty of people on these forums started later than that... and I still maintain that you're not old until you start acting old.
Personal recommendation is get impact shorts - you'll fall on your ass a lot as you learn (and progress) and it'll save you a lot of pain. And wear a helmet, I whacked the back of my head pretty hard a few times and was glad I had one. Additional protection is optional, I wear knee pads and wristguards as well, and I'm still in my 20's, lol.
