As an initial point of departure in addressing these specific
questions, you may wish to look at the following (somewhat dated) material:

Adams-Webber, J. (1979). Personal Construct theory. NY: Wiley;
Chapter 2: "Evaluation of idiographic contexts of meaning-repertory grid
theory and technique" (pp, 20-22); "Elicited versus supplied constructs"
(pp. 23-27); "Meaning and implication" (pp. 29-31); "Assessing individual
conceptual structures" (pp. 31-36); "Construct and figure interactions"
(pp. 36-41).

This is not a plug for my has been out of print for some
years now.
