Brush Help

I searched through the memories and couldn't find what I was looking for (unless I am even more blind than I thought). So, I have two questions.

First question is: I have millions of brushes downloaded into PS CS, so many that the list goes off the screen. What can I do to fix it so that it doesn't, without removing them? Is it even possible? I have good brushes at the end that I would like to use but can't reach. Or would you suggest just clicking Load Brushes rather than using the menu?

Second question: What, if any, PSP brushes can be used in PS CS? Image packs are such a hassle it seems. I was just wondering.

Thank you!
