Might anyone be able to provide a simple example for applying a texture to a point or quad (prefer point sprite if possible - less work??).  Then load all the vertex data into a buffer, load all the texture points into a buffer, colors, etc.  I'd really like to start using a VBO for my textured particles.  I'm somewhat familar with creating a VBO, I do it for my lines.. but just not sure how to do it with textures.

I'm using this to load my texture.
Code:

 try {
    particleImg = TextureIO.newTexture(new File(dataPath("particle.png")), true);  
  }
  catch (IOException e) {}
//.....
nodeList = gl.glGenLists(1);
  gl.glNewList(nodeList, GL.GL_COMPILE);

  shader.startShader();
  particleImg.enable();
  particleImg.bind();
 gl.glBegin(gl.GL_QUADS);
for (int i = 0; i < Nodes.length; i++) {
 Node n1 = Nodes[i];
		gl.glColor4f(0,1,1,.5);
		gl.glTexCoord4f(n1.x, n1.y, z, n1.w-5 );
		gl.glVertex2f( -1.0f, -1.0f );
		gl.glVertex2f( +1.0f, -1.0f );
		gl.glVertex2f( +1.0f, +1.0f );
		gl.glVertex2f( -1.0f, +1.0f );
}
 gl.glEnd();
 shader.endShader();
  particleImg.disable();
  gl.glEndList();
