Explain to my why the freezer will leak refrigerant when it is off but
not on.

This would most likely be a pinhole leak in the evaporator (inside the
freezer where the moisture and corrosion are). When running, the evaporator
is at quite low pressure in a freezer.

Question two)

Sometimes when I go to restart a freezer after it is off for a few
weeks or month, it does not want to start. The breaker in the compressor
just keeps cycling. Usually after enough time passes It finally starts
and will run fine from then on. Why?

When left idle, a lot of Freon dissolves in the compressor oil. When the
compressor fist starts, the oil sump is in the suction side and the pressure
drops, and that refrigerant explodes in foam, like opening a soda bottle,
and floods the compressor. This can cause the compressor to have a heavy
load before it even gets up to speed, and possibly stall.
Question three)

I would like to get enough education to be able to add
refrigerant when a freezer needs it. The electrical part I have a good
handle on, I have gauges and have no problem installing a Piercing type
Shrader Valve.
I need to know how to decide if a problem is caused by low
refrigerant, I'm not one to just do something because that's what I
know, I want to troubleshoot and come to a logical conclusion.

Has anyone seen a good video that helped or a book that is
focused on home freezer?

Well, you should take the online test and get an EPA green card so you can
legally buy the refrigerant. Then, you need a gauge set. These have
temperature saturation values on the dial as well as pressure. You fill the
system with the right refrigerant until the suction pressure is at the
proper value, indicating there is enough liquid from the condenser to
maintain steady, metered flow through the capillary tube. You also monitor
the discharge pressure of the compressor so as not to overload it. You have
to let the system settle into the steady state condition, this can take a
LONG time with a freezer.
