You are so welcome!
I did camp in the cold over New Years Weekend.  It dropped down into the 30s at night.  I bought a form-fitting set of thermals on amazon and a new pair of socks too.  I also used a mr. buddy heater when I would get back into the tent at night from going to the restroom.  Just turned it on for a minute or two and then turned it off and crashed back out.  I also added a thin thermal blanket on top of my sleeping pad and I was definitely warmer then before.  Thank you so much for checking in!
Also, I waterproofed with 303 Fabric Guard.  It was dry and cold when I camped a couple of weeks ago, but I am looking forward to seeing the results soon.
