Just finished ShB 5.0 msq, now I am somewhat lost as to what should I do before EW launch.

Should I spend my time finishing and unlocking side contents instead of grinding end game to raise my ilv from 430 to 530, which I assume will become obsolete once EW launch with level cap raised?

After getting to 5.55, I have plans to save up some tomestone to buy lv70 gears for the 2 new jobs. So that's for sure is on my list. Given such short period of time left, what else should I prioritize?
