You can do a lot at home to prepare.
Teach the 4 rules before going! Loaded, destroy, trigger, target. See how easy that was?
Show her how to operate the gun(s) at home. Dry fire a little. Not so much it is boring, but basic familiarization with no pressure, nobody watching, and no noise from the 30-06 down the line. It also breaks up the info dump into smaller chunks.
Then the time at the range (and your friends’ time) will be better spent on shooting.
I agree with starting off with a bolt gun on a bipod or front rest. Each shot should be learning. Start with sight alignment and sight picture (simpler for dot or scope).
Trigger control is the most important skill after safety. Squeeze, follow through. When you get to semi, teach that reset is intentional and controlled.
Then work on rifle starting low ready. Finger only on the trigger and safety off only when sights on target. Act like an RSO (while your friend teaches maybe) - someone should be watching the muzzle and trigger finger like a hawk until she has shown she can do it well. The other two can praise her shooting, watch the targets, etc...
And speaking of targets, if you have any steel plates, use them. The instant feedback of the hits is very gratifying. And take lots of 22. It is cheap.
When you get to pistols, teach a good grip up front. And remind about sight alignment/picture, and trigger control.
Take her to a 2-gun rimfire match. It will be a blast. Or shoot rimfire in a steel challenge match.
Take her to an Appleseed weekend (appleseedinfo.org) and you will both get great and inexpensive rifle instruction and practice.
That should keep you busy for a while.
At some point, if she is interested, certainly let her try centerfires or shotguns, but don’t push it on her or push her to do more of it if she doesn’t like it up the first time. A larger heavier (metal) 9mm is probably a good centerfire to start with. HiPower or M92 or 1911 sort of thing. Much more pleasant with softer recoil. For rifle, an AR is a no brainer if she is familiar with a S&W 15-22. In both cases, start off with 1 and then just a few rounds per magazine.
I have raised four kids shooting (starting much younger) and RO’ed and coached countless kids at various events and matches.
