Any help appreciated.....

Been fumbling my way through settings etc for a number of years with some ok results and some not, went on holiday to Vegas last year and decided to take the camera, took some on auto and some on manual etc, on auto the night and even some of the day shots were just ok, visiting again this year, any advice regarding settings, followed the instructions I got with it but failed miserably as it's not a place you can just stop and have a read of the booklet.Thanks
