I don't know how to build wheels, does this hub come in a pre-built wheelset?
Yes, this hub is built to our Box One Pro Rim with Box One Pro Spokes In our Box Three Wheelsets.

What spoke lengths should I use when building this wheel to a Box Rim?

We have published recommended lacing patterns and spoke lengths for all Box Hub to Box Rim wheel builds on www.boxcomponents.com/service

Can I radially lace this hub?

No, Box does not recommend radially lacing on any Box Components hub.

What should I used to Clean this hub and the internals?

The internals can be easily dis assembled by removing the drive-side lock-nut; the internals can be wiped down with a lint free rag and mild de-greaser and re-greased with a light amount of grease on the outside of the pawls. Too much grease could cause the pawls to stick or skip. Only disassemble if an issue is present.
