Yeah sign up for that Driver's Edge, Jan 25/26, there's still spots in green. How much wear you put on the car is up to how deep you get into the hobby. The first weekend in Green won't be that bad. Just be aware that if you leave the car bone-stock (which isn't a bad idea the first time out), and you get to push it around a little hard in the green group, you might get into issues with rising oil temps and brake pad fade. As long as you keep an eye (on the oil temp gauge and how the brakes feel) and maybe take it easy for the final couple laps of a session when they're getting too hot, it'll be fine. The instructors at Driver's Edge are all nice people, and there's multiple classroom sessions for green as well - they'll walk you through everything else you need to know.
If you're unsure about the state of the car (I assume a 2011 was bought used), you might want to at least replace the brake fluid with some RBF600, maybe do an oil change if the oil in it isn't very fresh - and be sure to download the tech inspection form and get a good local shop to go over the car and sign it off.
