Like Flip says the Haynes SS/Monster manual is ok for most things. You may find factory workshop manuals are also available on CD from ebay for about £10 usually. Most wiring is usually adequate but like he also mentions the alternator wiring is a known weakness and if I were building a bike like yours I would replace all the yellow wiring and plugs from the alternator with something more capable of handling the current without melting.

The battery starter leads are also another issue where replacing with better quality wires will make starting much easier. You can probably find something suitable in Halfords but more expensive specific Ducati model kits are available from Exact Start or similar.
