I wouldn't bother with Get to Work, because the careers don't work anymore, at least for me they don't. One pack that I do still get a lot of uses from is Get Together. Now to the reason, I say this, at first when I first started playing that pack it for the whole party scene, but not anymore. I am one who plays the family setting, mostly normal families. One aspect of the pack is the Club System, which I have used for keeping my sim's extended family connected. I have also used the club system for broken households, to get the parent who does not live at home anymore, to get them to come over with a simple click, and keep them around until I was ready for the parent to go home.
Other packs to keep in mind would be Island Living (very mind winters) and Snowy Escape (a snowy winter wonderland). They would make very good vacation locations, and your sims can even live there if they choose.
If going green is something your sims would like to do, then Eco Lifestyle might be something worth looking into.
