I am interested in textures.
Where are they located? In a PK3?
Yes. In pak0.pk3 you'll find all the standard quake 3 textures. They are inside subfolders in the folder "textures".

Can I view them ALL in Radiant at once?
I'm not sure if you can.

Is there a website with good textures that hasn't been taken down?
try cgtextures.com

Make your texture sizes in powers of 2 (eg: 1, 2, 8, 16, 32, 64, 128, 256, 512).
I think most textures in Quake 3 are 256x256 or something like that. By default, every two texels (pixels in a texture) map to 1 unit in-game. You can change this in Radiant and create higher resolution textures for more crisp texture detail.
I'd suggest you make all your textures JPG, unless you need an alpha channel (for transparency). Then use TGA.

Why do some textures do stuff? Like the water texture that creates a pool?
That's shaders you're referring to. A shader is a piece of text (a script) that describes 1 or more layers where each layer can refer to a texture. It describes how these layers should be blended together. It can also apply effects like stretching, rotating, animating, etc. It also determines properties like whether or not it's water, fog or lava and what type of footsteps you should hear when you walk on it for instance. Open up a .shader file in a text editor (also in pak0.pk3 in the "scripts" folder) and examine those. There's a detailed manual on shaders
here.
