But you have to know one thing : the texture needs to be "parallel" and can follow itself. Like if you put two brushes with the same texture side by side, it should have no difference you know ?
The term Pr3d4t0r describes is called "seamless" textures.
When working with textures it is recommended that you convert them to .dds format, which can be done in either gimp or photoshop using a downloadable plugin.
This wiki page describes the different available texture-maps:

I think you should use the "soliddiffuse" setting instead of decal too
Play around some with MaterialEditor.exe, you'll quickly get the hang of it.
