If you are anything like 99% of us, it is likely that you will end up adding more things so your notion of a fuse block makes sense. A lot of folks use one made by Eastern Beaver. There are other brands from places like Twisted Throttle. They all have easy attachment points that are either "switched" or not.
When it comes to installing it you might consider finding a neighborhood bike shop and ask if you can watch.
As he said. It's worth your while to fit a fuze block (I have the EB PC eight)that way once fitted you can easily wire in other extras, can be always on or switched. Takes all the connections off the battery terminals.
