I want a solid-state-drive (SSD) for speed but since they degrade when written to, I want to keep frequently written/rewritten files on my old HD.

  1. Is there a common arrangement already available to isolate boot and program files for read-only (like run from DVD) ?,

  2. Will I be thwarted by latest-access stamps updated even when their files are only read/executed ?

there's a few tweaks that are recommended.

I'm a bad use case, I don't usually use as many partitions as is recommended, but I would put my /tmp in ramfs most computers have more then enough memory for this.

and /home I would put on a regular drive.

your programs/configs don't change that often. IMO I think your $HOME changes a lot more frequently, and /tmp is written frequently which is why I allocated some space in ram.

These aren't necessarily the best choices, just what I've done myself.
