EditorGUILayout placement options?

Hullo, I'm having a bit of a hard time understanding the whole EditorGUILayout thing. Basically, I'm making a custom editor for my Spell class with a list of custom-drawn Effect objects. Right now I can draw each Effect using EditorGUILayout, and it shows up as a bunch of nicely-arranged variables. I have two questions about this.

1. What I want to do now is to put each drawn Effect inside a little box so it's easier to tell them apart. Is there any way to do this using Layout, or will I have to write everything out manually using plain EditorGUI?

2. Once I have these nicely-arranged boxes, I'd like to be able to click on one to select it, and then move it up/down or remove it via buttons. Is there any way I can make the Effect box "selectable"?
