Get CPT up for Rumination. It consumes Inner Quiet stack but restores CP accordingly in case you need to pump more touches or restore durability.
LTW's Waste not is a good alternative to "restore" durability.
ARM's Rapid Synthesis is alright, only 50% chance base and it can miss even with Steady Hands II.
BSM's Ingenuity helps when you need to craft items higher level than you, like say level 25 doing level 25 leves that requires recipe lv28.
You should aim to max out CPT for Byregot as that is a big boost in HQ and get CUL to 37 for Steady Hands II which enables you to 100% Basic Touch and use that to raise Inner Quiet stack. SHII costs 3 more CP than I and has 10% more chance.
Other 50 skills are nice but not required to level.
