Well Firefox 2.0 doesn't have the spell checker automatically built in, you have to download it and install it, or at least I did the first time I installed (I haven't yet bothered the second time, hence I manage to make typos) Hessiess, I probably would use the FF spell checker because not only will it help people understand you, its corrections may help you pick up the spellings better. As for the spelling of commands, perhaps copy and paste it into Open Office and get it to spell check it for you, that should reduce syntax errors.
As for program for beginners on there, dare I say it, C++, okay, not the easiest app, but you have so many resource out there for Linux, Windows and Mac OS, so find a Linux C++ IDE (The in the MinGW or something like that compiler and I'm sure someone has made and IDE for it) of course if you want to make games you'll want a SDK - Irrlicht is a good bit for 3D stuff, which is pretty easy to use and set up (at least in windows) if you do need to get started in linux with it, their forums are quite helpful.
Also I took their beginner tutorial and made my own elaborations on it, which you can find here:

I can't answer any questions on set up, getting a Linux C++ IDE (though I think it would come with one) or using Irrlicht under Linux, just how to code with C++ and Irrlicht. If you do have problems getting started, again, the irrlicht forums.
