If you're starting your stock with juvies, then the two 304Bs will be fine for awhile. Ultimately, you'll want to add a 3rd large filter. My 180 has been running for over 3 years now. I started out with two 304Bs and a year later, as my stock grew, I added an Odyssea 700CFS. Water is always clear and never had a single issue with water parameters.
In regards to heater: what is the typical room temp of the room your tank resides in? My 180 is in an unheated basement, where winter temps gets into the 50's. I run 3 heaters, totalling about 800W, connected to a Finnex temp controller. Holds water temp at 78F without a problem.
