As a note, if you go to Third Place, last I knew, the 121 Towne building has a daytime public section of it's garage on the Towne street entry level, as well as some street parking. So you can probably park there for Third Place. You can see Third Place from the garage entrance. (Although if you make a day of being in Stamford and have other things to do, you may want to park at one of the other places mentioned to keep your car more central and walk most places).
