It  is bettter to daven with a minyan even if one’s clothing are not dignified (obvious work clothing, for example) than to daven alone with properly dignified clothing. (This is a statement about the importance of davening with a minyan.) The same holds true regarding davening within the zeman Tefillah (even for shacharis, before zeman Tefilah, and not rely on davening before chatzos.) THIS HOLDS TRUE EVEN FOR WOMEN–so better in a robe, making zeman Tefillah, than to get dressed and miss it.
 
Talking during davening, besides everything else, causes a chillul HaShem, since it indicates a lack of respect and/or fear of HaShem.
There is no specific mitzvah to light Chanukah lights anywhere but one’s home, no matter how public and how much pirsumei nissa would result.
The only exception is lighting neiros Chanukah in Shul. Lighting in Shul reminds us of the lighting of the Menorah in the Beis HaMikdash, as the Shul is our Mikdash me’at, a miniature Beis HaMikdash (this is one of several reasons given for the Shul lighting).
