I think your points are valid, but I draw a different conclusion from them.

Our young lady friend, (if she's still with us :o), is likely to have trouble concentrating on chord fingerings and progressions if she's trying to nail her favourite band's sound.

Having said that, your gear selection is great for new stuff. If she can bring a knowlegeable friend along for a few safaris, she can probably save quite a bit at a pawn shop, or the used gear section of a music store.
