Almost all those cross class skills you had before you still have. They've been moved to each class's action list, at lower levels than they used to be available in many cases.

If you're feeling like you're struggling, make sure you're using Innovation,Ingenuity and Waste Not. Those are extremely powerful tools.

Level 60 scrip gear is still powerful enough to get you to 70. The only place where gear is awkward is at 50. It's not that difficult to push your way through the first few levels of HW crafting so you can get access to that expansion's leveling gear.

Also make certain you're putting basic melds on your gear, especially Cunning. New crafters underestimate just how helpful having an extra 10-15 CP can be.
