OT-Trip to NM advice?

Hi, I'm planning a trip from Palo Duro Canyon Tx. on roughly July 16-23. I am traveling with a DH that is vacationally challenged and a 14 and 11 year old boys. We planned on going to Roswell and Carlsbad. Any advice on places to see, or things not to miss? I would like to see some of the cliff dwellings, are any of the cliff dwellings just as good as any other? Never been to NM and would appreciate any advice...Would also like to take the boys to one of the Indian Reservations if there is a particularly good one to recomend... Thanks
