Thanks for any advice on these many questions !!

James,

Have you thought about using those stackable, mortarless, retaining wall
blocks instead of the landscaping timbers? They'll last a lifetime and
are just as easy to install as landscape timbers/railroad ties. I find
myself having to re-do all of my timber projects after about 10 - 15
years because of failure of some type rot, insects, etc.

The blocks are made in a variety of sizes. You'll find them in the same
6 inch size as the timbers you're looking at. You can build a wall as
high as 3 feet without having to use a poured foundation.
