You mention that you are at the beginner level for security things, so I will deviate a little bit and say that you should probably get certifications in the areas of security that you aren't as familiar with at first. If you have 10 years with windows, start studying and working towards a certification in something you aren't as familiar with before going for CEH or any of the pen testing certifications. Shoot for the RHCT or an LPI certification and get yourself more familiar with a *nix environment as a lot of the certifications ask you a lot of questions that you will mostly know the answers to if you are pretty comfortable in *nix. From there, the Security+ is more heavily focused on the technical side of things and will get you a little deeper, once you are comfortable there, I'll again deviate and say that one of Ed Skoudis's SANS classes isn't a bad way to go. I've taken 2 courses from him, and I felt like I definitely knew a lot more leaving than I did going in. At that point, you should know enough to figure out what direction you want to take, whether it's going to be corporate security, pen testing, consulting or something completely different.
Hope this helps.
