What are your stats exactly?Other then byregot being absolutely mandatory (you already have SH II) the other abilities are not a must but most will greatly help.
If you post your stats we can figure out some rotations and abilities that would be best for you to get first.
Note that the artisans off hand gives a lot of stats, so you are probably already capable of crafting them at a good rate once you got Byregots.
Once you have Byregot youll be looking at a rotation something like this:

The only level 50 abilities that requires is CF II and Byregot's Blessing. You should be able to do it with a pretty low craftmanship level as well.
