Thankfully, you can't.  If I remember the why correctly, it's because
this kind of thing shouldn't be up to individual apps, but instead the
theme should be in charge of it.  Although, I don't know if it's
modifiable even at that level at this point though.  All in the name of
consistancy my boy.

first, create the column, then create a renderer, then pack the renderer
into the column.

column = gtk_tree_view_column_new ();
renderer = gtk_cell_renderer_pixbuf_new ();
gtk_tree_view_column_pack_start (column, renderer);
renderer = gtk_cell_renderer_text_new ();
gtk_tree_view_column_pack_start (column, renderer);

or you can just do the gtk_tree_view_column_new_with_attributes (...);
with the first renderer and pack_start() the second.

I'm not exactly sure what you're asking with the last question here.
gtk_tree_store_set is just about setting the data that will be rendered,
you need to map that to attributes of the cell renderer using
gtk_tree_view_column_add_attribute() or
gtk_tree_view_column_set_attributes()
