I have a few 12v appliances, plus the lights that I would like to run off my battery. I'm wondering if I can run from my battery to the Breaker panel without a voltage regulator?
Not only can you, but you should NOT have a regulator inline ! All 12VDC appliances can tolerate a voltages up to almost 15V !

If my 12v refrigerator kicks on, will it cause my lights to dim or turn off?
Not enough information ! What kind of refrigerator is it and how much current does it require ?
If you are wiring from "scratch", your 12VDC distribution panel should probably have one circuit/fuse for lighting, one for "general" outlets and another for the refrigerator.
