Lighting Glitches?

So, I've been having some issues lately with lighting on my map (cp_armsfactory, shameless self plug). Mapper friends of mine weren't sure, so I was hoping some people here would have some ideas.

There's spotlights above the lit spots (light_spot and point_spotlights) above them. Do I just need more light or expanded angles on the light_spots? Or just some regular light entities on those spots to brighten them up?

This one I do not get. Again, light_spot and point_spotlight. Here's the thing though; the glitch isn't at a border. That's one brush that it's hitting, yet it suddenly cuts off. What do I do?

Displacements divide up their lightmaps in odd ways, so if you have displacements that are different sizes next to each other the sharp lines will happen. Displacements also tend to have very low lightmap scales so you can get blotchy effects like the first image has. That's mostly a contrast thing and your map looks waaaay too dark, so that probably doesn't help.
