Brush questions

[NiteX]

So most of the time I don't realize how big I made my map until I preview it and run around. I realize everything is way too big. So I select all my brushes and scale them down a few points then build. Well the problem is that the brush wire frames don't move anywhere but my level geometry does. This is a very big problem when it comes to aligning static meshes and other parts of the level. How can I fix this?

Ok I realize what I need to do but I don't know how to do it. I need to make all my brushes grouped and become one. I have them grouped but I don't know how to join them together as one.

Hold Ctrl and select them.

Yeah it's not that simple, I truly wish it was. All of the brushes are selected, but they are not as one. In order to become what they must become! They must be one!
