Firewalls... I haven't really found much INTERNET sources helpful (I've looked around a lot). I know of two GREAT books however that are not new but they are VERY informative.
Real World Linux Security: Intrusion Prevention, Detection, and Recovery by Bob Toxen (This is more of a general security book)
Building Internet Firewalls by D. Brent Chapman and Elizabeth Zwicky from the O Reilly series
You may be able to t*rrent them
(I do not condone this, I suggest buying it!)
As for using a Linux OS. Well it depends on what you want to do. I hear the best beginner type of Linux is Ubuntu. Things to note are:
1. Linux is open source; 99% are free and downloadable. I would suggest Ubuntu however since you are a bit afraid hehe. I would say goto ubuntu.com and obtain an iso.
2. I came in under Ubuntu 5.x or something, I believe they now make a way for you to try Ubuntu as a windows program. I say get a copy of ubuntu and burn the iso to disc and run it. See how you like it. If you plan on installing it, you'll want to read up on dual booting and finding if the drivers are available for your computer hardware. Also back up your data just in case...
3. Building applications in linux- You may want to look into programming. If you are looking into compiler-compilers and computer language, you may want to read bison and flex. You'll want to get comfortable with the *nix system first, but goto sourceforge.net to see how most projects are constructed. You'll have to read how programs arae built, configured, and installed.
4. You will want to learn the linux/shell commands first ( I believe bash is the most common shell) once you get linux installed.
I hope this is helpful
