She has been asking a lot of the same questions, which can be annoying to a lot of people. Personally, I don't have a problem with it. It's obvious she wants to help her friends have the best experience they can have...which is a lot of responsiblity.
My advice to you, Blaire...re-read all that's been suggested and take it all with a grain of salt. As many here have already said (and you admitted it yourself) your plans will be thrown out the window on the first day. Now you have a rough list of strains to try...so you'll just have to have everyone try them all and then buy more of what is agreed upon to be the best "bang for the buck", so to speak
Most importantly, don't stress yourself out with all the responsiblity and just have fun and be safe
