One of the main snag's when you head's stuffed full of windows/M$ shit it that I found it create's a kind of mental block.
The way I got round this, was to try and do everything as I would when using windows, if it turns out that you screw something up, then as long as you've got your install disc's then use the newbies tried and tested "cure all", re-install.
Normally this is a problem when you've become comfortable with a linux distro, because you end up with shit loads of data that you don't want to loose, but as you're at the earlier stages, it probably doesn't present too much of a problem.
Now as for "idiot guides", well, I've never managed to find anything that really "fit's the bill". There are a few things about for specific app's, and if you had the money, there's mandrakes own "definitive guide to ......" (you should be able to get the 9.2 version, except for the money issue).
If you look at my sig, you'll see a link for "Rute Users guide". That's got quite a lot of stuff, but some of it is written in "geekspeak".
There's also the man pages. I suspect that you'd have those installed by default, the only real problem is that again they are in "geekspeak". So if you check the links in my sig, there's also one about how to decypher them (erm, you just need to open a konsole/terminal - the tv screen icon, probably on your task bar - when the terminal open's, you can just type
which is the man - manual - page for man pages).
if you want to try and do something, but you get told that you need root priviledges, then is you are in your user account, you open a terminal and at the prompt, type su (switch user) and then put in your root password - but the downside is that you have to do stuff via the CLI (command line interface). If you want to do something in a graphical environment as root, then you'd usually have to log out of your user, and back in as root for graphic root access.
Finally, "google is your friend". You can either go straight to google and just put whatever you need to know about in and search, or for more specific linux related stuff go via http://www.google.com/linux
Sorry if that all sound's a bit vague, but I've spent over 2 years looking for a good "idiot's guide", and failed dismally. And yes, it often still confuses the hell out of me.
hope this helps a little.
