I'd skip Pizza Rock. We ordered three different styles of pizza there on my 50th birthday and they all failed to impress.
My in-laws just returned from a week there. They asked the same question you did, so here the suggestions I sent them:
Daytime Stuff: Mac King Comedy Magic Show, , Mob Museum, Wayne Newton's Casa De Shenandoah, Clark County Museum, National Atomic Testing Museum, Gold & Silver Pawn Shop, Rick's Restorations, Count's Customs, The Auto Collections at the Imperial Hotel, Bodies the Exhibition at the Luxor hotel, Titanic exhibition at the Luxor, Jeff Civilico Comedy in Action at the Flamingo (check performance times; sometimes afternoons, sometimes early evening
Cheaper PM shows: Louis Anderson. Comedy Show, Vegas! The Show at Planet Hollywood
Food: Grimaldi's Pizza (multiple locations including the Pallazo hotel; good for lunch or dinner) , Shake Shack Burger, Mesa Grill (Bobby Flay's place), all the food at New York New York is good, Bellaggio dinner buffet
