As so many of BRD's skills/procs are dependent on crits, Critical Hit is probably your secondary stat of choice.

At your level, if you're keeping up with your job quests, you'll be getting some pretty ok left-side gear at 45/50. MSQ will also provide plenty of appropriate gear as you wrap up level 50 quests leading to Heavensward content. If you'd like, you can save up tomestones of Poetics to spend in Mor Dhona for ilvl 120 Ironworks gear (which you can also upgrade to ilvl 130 Augmented Ironworks in North Shroud), which will be the best available gear at 50, and serviceable until level 55 at minimum (some players will push all the way to 60 with this gear, when they can buy the next set of Poetics gear, the best available for level 60).

Far as tips go, you lose nothing by having songs playing, and you'll need to keep those DoT skills up to get the most out of them.
