If you have access you need to secure it about every 48". If you're fishing it through walls then there's no way to do that.
PEX touching wood is not an issue. Foaming will work just fine if you want to.
Water hammer isn't such a big deal with pipes that can flex like PEX does. You still need arrestors at fast acting valves in my opinion...Dishwasher and washing machine, but I wouldn't bother putting them anywhere else.
