What code/assets should I use for 2D apps?

So I plan on making some 2D apps currently with Unity. I have a couple ideas, and am exited to work on them. Now, I have a few main questions...

1) What should I use for scripting? I was working towards learning C++ when I realized I can't use that with Unity. I have no C# experience and a little experience with Javascript (w$$anonymous$$ch I've heard Untiy's JS is different, so have been looking up video tutorials along with a nice one I found on the forums.) So basically, for making simple 2D games should I learning Unity's JS or should I learn C#?

2) was going to use t$$anonymous$$s guide some... http://maniacdev.com/2012/02/developing-2d-games-in-unity-3d-without-paying-extra-for-tools due to the fact I have no money to spend :P is t$$anonymous$$s a good place for a noob like me to start? Any other suggestions regarding free tools I should use to make it easier?

Thanks for your time, sorry if some of t$$anonymous$$s has already been answered somewhat somewhere but I honestly have been Googling stuff for a good solid three days.
