Sounds like you're already doing a lot.
Might not directly get you a job but I've found it can't hurt, start a blog and write up anything you're are doing whilst studying and learning; new tools & techniques etc. (I know, hated the idea when I started).
As well as helping you retain the info by having to write about your understanding, it can also get you involved in the community and provides a stage to show employers what you are capable of and help you stand out from other applicants.
If getting a security specific role is difficult, look at an admin or support role in a smaller organisation (<250 employees). You'll be amazed at the number of other techies that are delighted to pass off the 'boring' security tasks if you show an interest

Hope this is of some help, good luck out there
(& twitter doesn't hurt either...)
