Yes, that's a good list. That hits all the bases without leaving off anything crucial, nor adding anything extraneous (like, for example, "supports the flat tax" or "supports the Fair Tax" or "will privatize Social Security", for instance).
Unless you intend that support of the 2nd Amendment is covered under "Limited Government" I would say that a clear statement of support on the 2nd Amendment would be a requirement for this conservative voter.
