Yet another newbie plumbing question :-)

So I have most of my pipes back where I want them. In one place I
come out of the floor with a hot water pipe, elbow, elbow, elbow,
connect to shower valve. I tee out of this and elbow, elbow, elbow,
and stick out the wall for sink (I know, hard to picture exactly
what it looks like, but there are about six elbows total because
that is what it takes to get the pipe where it is needed lol)

Question - if I secure the pipes to the wall here and there, will the
stress of warming and cooling pipes that are fastened to wall and
have a bunch of elbows here and there cause premature failing, or is
the pipe strong enough to take the stress? I'm using copper, rigid,
3/4 to shower valve, 1/2 from the tee to sink valve.

Leave a little slack in the supports so the pipe doesn't get clamped
tight. The idea is support, not rigidity. also place your supports
such that minor expansion is allowed, like away from the tees, other
fittings. If your soldering techniques are good, there will be no
problems.
If you have doubts about your skills, there are some pretty good video
clips on YouTube that will be useful.

And use copper or plastic supports. You don't want steel in contact with the
pipe.
