Two things:
One, those bombs are not made by any monster, they are so-called "trail bombs" set in the level. With "Deadly Gift", you can use them too, handy little suckers. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> Best way to deal with them is to run into an area, and then run back out. You can USUALLY outrun them, and they don't navigate corners at all well. (With any luck you'll trip across a few in your travels.)
Two, the best way to deal with the room full of enemies is to run for the nearest corner. Despite what the cutscene implies, the monsters will not in fact ALL run for you at once. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> They will only attack, like normal critters, if you're within their sight or hearing range, so isolate groups of them to pick apart at your leisure. Divide and conquer and all that. Once you get past the initial large group of enemies, the rest is easy because you can lure them to you in ones and twos. Heck if you run fast enough you can take the initial group in smaller doses too, they'll get strung out chasing you.
Anyway, good luck, or hope you managed to survive it okay if you passed it already. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
