They may have decided on the 45-degree angle after Apollo 9 and
before Apollo 11, since they did a lot of experimenting during
the program. The panels weren't detached from the booster at all
during Apollo 7, but Wally Schirra complained that the panels
were flexing too much, posing a danger to the spacecraft when it
docked with the LEM during the transposition maneuver.

In the book _First Man_ Neil Armstrong gave his own version of
the panel explanation. He said one of the panels was off to one
side but had gotten sligthly ahead of the spacecraft at a
position where it would reflect a large amount of sunlight. But
Armstrong was speaking from memory years after the mission. He
was also recollecting how they knew at the time the object was
probably one of the SLA panels but didn't want to say anything
that would excite the "UFO nuts" at the time. That seems to be a
rather odd explanation, since if they knew it was a booster
panel and had  just told that to mission control, the UFO nuts
wouldn't have gotten terribly excited. In any case, the
debriefing transcript indicated that Aldrin had already
considered and rejected the SLA panel explanation at the time
and that Armstrong didn't object, so he seems to have
misremembered what they knew and didn't know at the time. So
perhaps Armstrong's memory was innaccurate on the position of
the object relative to the spacecraft, too.

That's an interesting point. If the spacecraft had been rotating
a full 360 every 20 minutes, it seems to me if it were a piece
of debris from the spacecraft itself, they should have been able
to observe its progress as it moved away from them and concluded
it had originated from the spacecraft. They also should have
been able to discern its shape without using the telescop when
it was closer to them. I'm not saying that proves anything,
though, since they just  might not have been paying enough
attention to have noticed a piece of debris when it was closer
to the spacecraft.
