Reply to New guy looking for lots of answers

First off let me say that these things are completely bad-@$$.

with that said I have sooo many questions. I just ordered 2 numark ndx 800s, a new vestax pmc 05 pro iv, a new soundcard NI audio 2. then I stumbled upon these beautiful machines,, and FREAKED OUT. I have sen that you all have lots of mappings for traktor, but
1.i was curious would with work with vdj7?
2.could I use a midifighter as a video mixer?
3.how hard are these to map?
4.are they hard to build?
5. where can I find the microchips to use? do they have to be midi fighter chips?
6. can the LED's be changed so you have more than one color? (instead of blue, maybe red and green? or blue and green?)
7. are these things really the coolest thing around?
8. Is it possible to just order a full custom midi fighter that is the size of two midi fighters?

I have seen some answers to these question out there, but I am really new to the whole midi world. I am an old school dj and really only upgraded because technics cancelled the 1200's and vestax did away with the samurai. I do alot of video work and believe a custom controller that could run all my video stuff would be AWESOME.
Sorry I know I probably sound like an idiot but I am still wrapping my head around this nifty little product.
I want to thank you all in advance, it looks like this is a really supportive community .
