Sure, there is one such group.
http://www.ilg-dresden.de/They meet quite often.
The folks here speak the Sachsich accent. It's no big deal though. If your husband is getting into any of the two big semiconductor companies, then there's little cause for worry since the companies also pay for the language courses of the spouse.
Dresden is a safe place. Some parts of Neustadt (around Alaunstr area) appear shady due to the numerous drunks, but they usually mind their own business.
It's easy to get around here since the tram/bus system is great. U-bahns are not present since the city size does not call for it.
Oh well..you will figure it out on your own soon.
Good Luck!
