help with layout of bathroom plumbing
Below you will find two drawings of the ruff layout of my project. What I am now hoping to start ruffing in the plumbing. If someone could provide me with what parts they think I would need it would be much appreciated.
Also the lav is a pedistal on an exterior wall the wall is a 2 x 6 wall but we live in a area that experiences winter my question on that is should I be concerned about putting the pipes inside this wall about freezing?
First is a drawing of how I was planning on the drain pipe. Black is 3 inch drain red is 2 inch drain and green is 2 inch vent.

For the lav and bath 2 inch pipe I planned on dropping it down into the 3 inch drain from the top not sure if this is how I am supposed to do it or if I am supposed to come in on the side of the 3 inch? Any advise you can give me on what fitting to use etc is greatly needed. Still a bit confused on how to vent the toilet can I just take and put in a 3 x3 x2 just under the flange to vent it? Sorry for so many questions just want to make sure I do it right the first time.
