I'd forget the package and buy your own stuff to top it off. If you can, skip the plain stocked model and go for the accustock. I think they may be standard now. I own one in 7RM with a plain stock and it sucks. Pretty flimsy. I'm betting the accustock doesn't suck so bad with some reinforcement. But in the end it shoots straight and I personally like the accutrigger, at its lightest. Can't speak particulars on ammo, as I've never shot factory loads through it but I've ran 120-154gr bullets through it, primarily hornady and they've all worked and it hasn't been picky at all for acceptable accuracy.
