Most of it is common sense. I bought a book on load securement and also followed the FMCSA book of regs. Pretty much everything you need to know is in there.
The shippers usually know the best way to secure their load if it's something they ship out all the time. When I hauled coils the shipper made you do it this way and no other way. When I hauled plastic pipe they make you strap half the load then strap the whole load.
You can ask and watch other drivers too.
Here is a link to the cargo securement book.
