Those lfs will do anything to sell damsels......They are aggressive and shouldn't be put in until the very last if you are going to put them in at all. They are almost impossible to catch once they are in your tank without tearing the whole thing down so be warned.
Do you want a nice community reef? If so good choices are flasher wrasses, dwarf angels (though some are reef safe with caution as they may nip corals) gobies, blennies, cardinals, firefish, clowns, chromis, and if your tank is large enough tangs
I would suggest making up a stocking list of those fish that you would like to have then let us know and we will give you good constructive advice on the stocking order, compatibility etc. Make sure that you research each of your additions PRIOR to buying them so that you know what their wants and needs are which is of utmost importance along with making sure you get healthy specimens that are eating well and show no signs of stress or disease.
