Stretched terrain texture and glare

I'm using an IndexedTriangleStripArray for my terrain mesh.  I give it a 
textured appearance, via the code, below.  The problem is that the 
texture isn't laid out in nice "tiled" pattern, like I might hope.  
Instead, it's rather badly warped & stretched, as shown here:

In addition, when I face toward the light, there's a rather undesirable 
glare on my terrain.  I used NormalGenerator.generateNormals(), so I'm 
pretty sure those are right...

Can anyone offer some hints about what I can do to correct both of these?

Thanks!
