If I start Davening a hour and a half before Chatzos on Shabbos, is it preferable to Daven slowly and Daven Shmona Esrai after Chatzos or to Daven with the Minyan at a faster pace?

 

The Rebbe encouraged even those who Davened Be’arichus to begin with the Minyan. Regardless, starting so close to Chatzos is itself problematic. You should begin earlier.
