I'm trying to build some views for my RCP project, and would like to try a BoxLayout.
The problem is that there is no "Struts and Springs" palette anywhere, and no way to adjust the boxlayout!

How do I get this palette?

I would not recommend using BoxLayout under SWT/RCP. There are much better choices available.

BoxLayout is a native Swing layout that has only been partially ported to SWT (no SWT Box class, so no corresponding struts and springs).

Use SWT GridLayout (best choice) or FormLayout.

I've tried GridLayout, but haven't succeeded in making it do what I want.
I have 2 Composites. I'd like one to be at the left, and the other to be at the right, both re-sizing width as needed depending on their contents.

Depending on the content and exactly what you want to do, GridLayout will do that. You can try FormLayout as well.

I'm currently trying FormLayout. I think I have it working correctly, though the WindowBuilder GUI is being confusing.
When I click on one of the Composites that is in the form, all the alignment buttons show up on the tool bar - and ALL of them are disabled.
If I right-click on the composite, I can use the "Quick Constraints" popup menu, and those seem to work.
The documentation talks about a "Floating Layout Assistant" - which I have been unable to find.

If you are using FormLayout, I would recommend turning on Classic mode.

Unless you have two or more widgets selected, the alignment buttons will be disabled.

You need to click the Layout Assistant button http://code.google.com/javadevtools/wbpro/layoutmanagers/swt/images/assistant.gif to access the Floating Layout Assistant.
