The command srst mode auto-provision all tells the router that when you
learn info from a phone in srst mode (via SNAP) keep that info in running
config. If you desire to keep all that info in running config you also
need to keep the command in when saving the config.
Althought I haven't tested it, I would expect that removing this auto
provision all (or dn) would also remove the dynamically learned info from
the running config but any command you manually typed (such as a hunt list)
would stay. If you let srst learn the ephone dn dynamically, then you
manually add a description (as in your original question) I would not
expect than ephone dn or description to show in running config after
removing the auto provision all.
The link below discusses the various srst options and gives many cli
examples of features you can deploy with cme as srst and using auto
provision all. I would suggest revieiwng these config samples to help
prepare for the lab.

I have heard the same advice for srst in the lab from several people:
configure srst, test it once and exit, then save and reload. Do not test
srst again, trust your config if it worked the first time. The reason for
this advice is that the older router code has some bugs and if you try to
enter/exit srst multiple times the first will work but it may fail on
subsequent tries.

Short answer - yes you need to save the config.
Long answer - if you want to ensure the ephones, ephone-dns, and
descriptions are all shown in the running config then you should save the
running config to startup config at a point when all the settings you want
(ie, description) are visible with show run. The two good ways to do
this are to manually type the config before entering srst and save, or
trigger srst then modify config as needed EXIT srst and save.
It is typically recommended to NOT save the running config while srst is
active (if using mgcp) because the mgcp-fallback process will remove
automatically remove the serial interface subcommand isdn bind-l3 ccm
when srst is triggered allow the default application (h323) to contol the
serial interface. When cucm is reachable again this same process will
restore the bind command to allow l3 backhaul of the serial port to cucm.
So, if you save your config while in srst and then you (or the grading
script) reload your router the bind command will be missing and the serial
port layer 3 will not come up until you manually put it back.
I just make it a habit to not save any configs while in srst mode, but if
you are using h323 there may not be any issues - someone else may be able
to comment on that or you could try it as an experiment and let the group
know how it goes.
