I looked at buying a board with plug in driver boards but couldn't find one that worked above about 36v. You might find that that is not enough for your choice of motors. The motors I used would have operated at 36v BUT I would never have got the best out of them so opted to go with 3 separate drivers that could handle a much larger voltage.

You will get lots of help with control box set up from members on the forum so don't let your lack of knowledge (at the moment|) put you off. Quite a few of the build logs have most of what is needed covered so reading them will give you a good start for your own system.
