Ok, before you make any more maps, you need to learn how to align textures.
Make a small map with 3 boxes -- each a different size -- and align the textures on them. In BSP, hit "S" to bring up the surface dialog. There are values for the scale and offset of the texture. Play around with them and get a feel for how they work, then align the textures on the 3 boxes.
Some tips: if you make a 64x64 box on a 64x64 grid, it's already aligned, you can then press alt-L to lock the texture and move it around on a smaller grid. On a 32x32 grid for a 32x32 box, you can do the same thing, but you need first scale the texture to 0.5 (both x and y).
Once you've done that, post a screenshot or the .map. Then we'll work on lighting.
