I couldn't figure out how to edit existing gradients. So I tried allocating a new one. And it seems to replace the old one. So I guess that will work. *shrug*
Here's the entire plugin code:

BaseMaterial *mat = doc->GetFirstMaterial(); // Get the first material and assign a variable to it
if(!mat) return TRUE; // Error handling
BaseContainer *data = mat->GetDataInstance(); // Get the material's container

k1.pos = 0.0; // First knot's position
k2.col = Vector(1.0,1.0,1.0); // Second knot's color is white
k2.pos = 1.0; // Second knot's position
gradient->InsertKnot(k1); //Adds the First knot from memory

I hope this helps any newbs out there get up running a lot easier.
The mode option is still broken. But I'm exhausted from starring at this thing. So I'm taking a break.
Thanks for the help guys,
