any tips would be great--
i am using NI battery as my main drum sampler (with hardware synth), but i just wish to know how to make the quality better and stronger.
when i have all the tracks together, the drum track becomes the weakest--not so clear. making volumes higher just makes the sound distorted.

of course, i dont have big studio set up, but would like to know anyways to make it better. do i need some kind of hardware equipment?

i am using motu 828 which is not bad at all.
suggest me anything--

compression, compression, compression....(and limiting) That will punch up your anemic tracks.

and download a copy of the Vintage Warmer - it's a beautiful thing. But beware, it really works your CPU - I'm only able to consistently get 2 instances on my 800mhz power mac...(running ProTools 6.1 - OSX)

Use compression right though: don't set attack to fast (try around 25/50ms) or you loose the punchiness.
also try cutting your bass in the 80 Hz region (eq wise) that's where the "thump" in the bassdrum is. Boost bit 2.5K/4K region overall on drums to make more snappy... Don't compress snare to much; you'll loose dynamic feel
