I would absolutely reccomend you to get Drumkit From Hell Superior. Although, you need 35gb of free hard disk-space, and a really powerful computer to use it.

Alternatively get BFD

These programs can both be used as VSTi's and, as far as I understand, are both pretty much set up and ready for using with e-drums.
Now, those reccomendations were not coming from experience. What I've done with my band for recording drums is pretty different because of a limited budget. I've used the midi out on my drummers e-drums and recorded the midi-signal from them onto my computer. Then, I've used the first (oldest) version of Drumkit From Hell combined with ns_kit7 (free soundfont/sample pack:
http://www.naturalstudio.co.uk/ns_kit7freedownload.html ), loaded into battery (sampler).
When we recorded the drums, I made sure that the midi-signal didn't peak all the time (velocity at 127). Before we started recording, the drums were set up in such a way that more or less every hit were at 127 on the velocity level. So, we fiddled a bit with the kit until it didn't peak all the time. This way, we got a pretty dynamic midi-track. It sounded rather bad and weak with the sounds from his e-drums, and before doing anything, it sounded bad on the computer with Drumkit from Hell/ns_kit7.
What I had to do was to use the midi-compression settings in cubase a bit until I got hard enough hits with the right dynamics. Because the initial signals were overly dynamic. After everything sounded all right, I exported the different drums to separate audio-tracks, and mixed them until they sounded decent enough.
It has worked pretty all right, but when I'm looking back, my way of doing things has been overly complicated and stressful. It has been and still is a whole lot more work than what it could have been.. I found very little info on how to do things on the internet, so I've had to improvise a whole lot in order to get a decent enough result. Surely enough, I've learned a whole lot from it, and I can't deny that it hasn't been interesting and probably somewhat valuable. But, without even having tested the software I would absolutely reccomend BFD or Drumkit From Hell Superior, because these are already set up and ready to go for most e-drum kits, and offer some of the best drum-samples that you can get hold of.
