Welcome!
I too moved here in February and have enjoyed the summer events along Lake Zug. I have found a couple of nice bars etc. Im Hof is quite nice for a quiet drink. I tend to avoid Pickwicks unless I want to watch the icehockey or rugby. An evening apero at the top of the zugerberg is also nice.
Otherwise we have tried bowling in Sihlbrugg (nightmare to get to via public transport) and pool in Cham - both ok but you do need a group to go with.
Also look at the Zug4you website, (in English) which does advertise some expat focussed events.
Let me know if you fancy a coffee sometime, I am off from next week for 5 weeks!
