Is there an equivalent of GDB's 'p' (print) command
(or access to the actual 'p' command)
that will print the value of an expression without adding a watchpoint?

Yes there are several ways. You can use the Variables view or the Expressions view.
The default debug perspective has a number of debug related views.
You can see what they are with Window --> Show View --> Other --> Debug
http://help.eclipse.org/neon/topic/org.eclipse.jdt.doc.user/reference/views/variables/ref-variables_view.htm?cp=1_4_7_6

A number of these are in the documented in the Java section. Some of them in the CDT section:

Hovering over a variable in the code will show its value.
The same for a highlighted expression in the code.

You can also issue gdb commands in the gdb console which should magically appear when you begin debugging,
If necessary, it can be selected in the console view from the drop down list named Display Selected Console when you hover over it.
