Can WebGL only render triangles?
If so, what approach should I use to determining which way I split quads into triangles?
Also, can you use multiple fragment and vertex shaders?
Lastly, I notice that some fragment shaders made for working without polygons can make some perfectly smooth objects. Would it be viable and sane to have models render with math opposed to geometry, using only a few polygons just for the sake of having their vertex shaders control that math?

I completely forgot about that game, I used to play it all the time. What's it called?

Don't know about WebGL specifically but I tend to use ear clipping triangulation. Or delauney if I get fucked up models but it's slower.

Try >>>/vg/agdg maybe?

You can split quads into triangles in a few ways:
1. Arbitrarily split the quad and stop worrying about it.
2. Choose the split that produces the largest angles in your triangles, since small angles give bad specular highlights. This is fairly easy with the dot product.
3. Assuming the quad is non-planar, choose the split that best matches the concavity of your surface. This can avoid "dents" in your surface mesh. This is much more difficult and requires you to estimate the surface gradient.
No idea what you're talking about in that last bit. Most of realtime computer rendering is triangles because they're fast. n-gons are a sin.

Yes you can have multiple shaders. Just change the shader before each draw call with glUseProgram()
