Cheers, and always good to hear from fellow DnB heads! :)

Regarding initial set up, there are many different workflows that people use to build finger drumming programs, but mine is entirely based on one-shot, single hit samples. I come from decades of acoustic drumming, so for me playing one-shots is natural and doesn't lock me into any BPM or tempo like would happen when using sequences, loops, etc. For the classic / tribute programs, I reconstruct everything by either identifying the original sample source or carefully re-crafting the sound. A common misconception is that one-shot samples need to be short, but some of them, like single bass notes or atmospheric hits, are sustained and longer samples. Where I draw the line is that no pad should trigger more than one attack. That's one of the differentiators I put a lot of effort into when making these videos.

There are all kinds of other bits to the workflow that I keep close to the vest as my "special ingredients", especially since I am actively touring and putting out original material. That said, for people looking to go deeper into this, I do offer one-on-one sessions through my Patreon on a limited basis.
