The reason you want HQ everything on turn-ins is that they effectively DOUBLE the XP reward. So, on the Star one... it's a massive bonus. Enough to bypass at least one or two leves.
EDIT : Stuff that's coming to me as I remember it -
1. Don't hesitate to cross class skills. Steady Hand 2 and Hasty Touch are the most important I'd say. 80% chance to raise quality without spending CP is better than 70%, especially for just an extra 3 CP on Steady Hand 2.
2. Each 5 levels you get an extra cross-class slot - Use it! Personally this is what I got (adjust for classes that already have these skills - I'm assuming you don't have 50 CRP and 50 ALC 'cause those I'd say Comfort Zone and Byregot's Blessing instead)
Level 15 - Steady Hand 2, Hasty Touch, Tricks of the Trade
Level 20 - Rumination
Level 25 - Manipulation
From there, I think you're gravy since those are the most important while grinding up some crafts.
