It is a reasonable guess you are not new to sailing, but you have a new to you boat. Congrats.
Running rigging. Are you thinking of total replacement or just some go the rigging?
In my experience, you really don't need much more than a tape measure, or the knowledge of the mast height for Halyards. The boat length is relevant for sheets.
The line you run on the Main, Jib, and any other halyard are usually the same type Low stretch line. You may go real old school and buy one big roll or you may choose the colored route. Different colors for different tasks.
The Main halyard is the height of the mast times 2 and any bit to run the line from the mast base to the cockpit if so designed. The jib halyard is the mast height (you have a mast head rig according to Sailboat data...)
and the length of the jib luff. Again add the distance from the mast base to the cockpit if needed.
Spinnaker Halyard would be the same length as the Jib halyard. If concerned you can always add 5 ft to the length. If the extra is not needed you can cut it off and use it on board to hold your fenders on the side.
Sheets for a Genoa are usually 1.5 times the boat length. The Main sheet depends on the number of turns (blocks) easiest to just measure. The Spinnaker sheets are usually 2 time boat length.
