And I have to use texture2DRec instead of texture2D, don't I?
Yes, that is very important to understand. All of the texture objects have to use the same mode. As already pointed out, once you use shaders the automagic selection of these types in GEM is no longer going to work properly. The user has know how these things work.
A copy of the GLSL 'Orange Book' might come in handy too.
