I currently live in Vegas and I enjoy it. I technically reside in Henderson though. The school system is pretty sad, but it has a lot to do with parenting -- unfortunately most of the population here works one to two jobs (and a majority of them work graveyards -- thats how it works with a 24 hour city), and unfortunately a lot of kids suffer because of that.
I love Vegas because there is sun almost everyday of the year. The cost of living is going down a bit. And nurses out here make EXCELLENT money and benefits; however, many of the hospitals have unsafe nursing
To the OP, any hospital out here is wonderful to work at. I would try staying away from the Valley Health System -- I've heard they are hell to work for. Otherwise everywhere else seems decent (the county hospital UMC is the lowest paying hospital -- new nurses start out at $21 there). Otherwise anywhere else you go, new grads usually start out between $23 - $26.
Furthermore, there is always something to do in Vegas/Henderson. I personally do not gamble and always have something to do.
