Correlation is the process of comparing and contrasting. Basically, showing how the the various pieces of evidence corroborate or conflict with other pieces of evidence. No rubric or definitive process is laid out here. Just suggestions of tables, timelines, maps, etc. Jones does say to group dependent pieces of information/evidence together.

Correlation is something that is done across multiple sources, so it needs too be done per research question, not per source.

Resolving conflicts & drawing conclusions is part of GPS items 4 & 5, not 3. I.e., do the analysis on each item and the compare & contrast separately from trying to resolve the conflicts or drawing conclusions.
