There are two separate things in your question. First , you build a cart (and everything you need to know about it , you'll find on this forum. You just have to read a lot). The second part is electric stuff and that is the same for all electric vehicles (in essence). Some information's you can find here and some on Endlessphere forum (for example) .That means that you'll have to read some more about electric motors , controllers , voltage , amperage , batteries , switches, fuses , throttles (well it is not a throttle , but you know what I mean) and a few more things...
Basically , there is no manual for that stuff, or "how to..." book , because everybody does it a bit different (depending on their skills , budget, available components...).
Research is the key. Good luck !
P.S. That motor of yours can be a bit tricky to implement on a kart , because of 180 V rating. It can be done by using a DC - DC converter , but somewhat expensive . You can (in general) over volt motor any time , but it's not healthy for it to put more Amps trough it, which will happen if you use less than 180 Volts .
