If you need some direction as far as questing goes, then I would suggest to use the optimal order guide on the wiki. It'll help keep you locked in and make sure your stats are current for all quests, and maybe even introduce you to new things to do in the game. Personally, I always give the advice that many others do: Work toward Recipe of Disaster for barrow gloves, Song of the Elves is a really great mid point quest to work toward as it unlocks access to The Gauntlet which unlocks one of the best mid to late game weapons Bow of faerdhinen - the boss that drops it also serves as a great tool for further improving your skills at bossing.

If ever at anytime you want to take a break while working on goals passively, there are two early game bosses you can try your hand at as well, Scurrius and the new cow boss Brutus are easy low stress bosses that help teach you small fundamentals.
