I should think that a guide for beginners would either include a glossary of abbreviations or avoid them. (ccw, owb, iwb)
I agree with most of what you say here but take exception particularly with your $2,000 price tag.
I spent barely over 1/2 that amount including the required class, 500 rounds of ammo, gun (Glock 33) and other equipment, and EVERYTHING I need for reloading, including bullets/primers/press/etc, for over 1000 more rounds and several other unrelated calibers/dies/bullets.
Drop the reloading supplies and I'd be at $1,000 or less easy.
Otherwise, I think you've got a good start there, even if a good portion is truthfully open to varying opinions.
