Blackburrow is a great zone for your level, but if you're starting entirely from scratch it can be a little rough. Some tips you may already have figured out:
The tunnels leading into BB from Qeynos Hills and Everfrost both have gnoll guards that are easier than the gnolls inside Blackburrow, and still have a chance to drop gnoll fangs (turn the fangs into Captain Tillin in South Qeynos for awesome xp), if you're having trouble staying alive inside you can beat up on the easier outer gnolls for a level or 2 before moving in
Qhills also has rabid wolves and grizzlies, these always drop diseased pelts you can turn into Priestess Caulria at the Temple of Life in North Qeynos for great xp and some okay plat. At 6 the grizzlies are probably too tough but the wolves should be pretty easy.
You can summon your corpse to you by targeting yourself and typing /corpse, it only works if you're close enough but the cool thing is that it ignores vertical distance; in a multi-floor zone like Blackburrow this means that if you die deep down you may be able to summon your own corpse from the relative safety of the top floor.
Lastly, I THINK Blackburrow counts as an outdoor zone, meaning you might be able to prevent some trains by casting Harmony on groups of mobs before pulling.
Good luck and welcome to EQ
