first, i wire all the common connections (ground, +/-v) between components on the panel--for wiring between componets (that therefore will never flex) i use solid wire, usually 24 or 26ga.
then i figure out what i have better access to with boards/panels all mounted: the PCB or the panel. then, with the panel detached, i add the wires to whichever (panel or board) is less accessible. then i mechanically attach pcb and panel and start wiring, generally starting with the shortest wires. i use very small gauge stranded wire, 26 or 28... if its pre-tinned, it seems to hold it's shape better when you try to route it. i try to bundle wires logicially into subsections based on proximity, and sort of color-coded: black for grounds, red for outputs etc. i'll often use ribbon cable, especially for pots and switches, splitting off bundles of 2 or 3 lines leading to a single control. and it try to route wires so they follow along the panel/pcb plane (rather than just flying thru the air), and tie them in place temporarily as i go. even after it's tested, i'll use twisty-ties to tidy things up rather than wire harnesses, which make it harder to do maintenance.
