Although some say it's not necessary to warm up your car when you're first getting started. What are your thoughts on that? From an efficiency standpoint, is it better to warm up your car for a minute or two? Or until it drops under a certain RPM's?

I think general consensus is to warm the car up by driving it. It's going to warm up over time regardless, and if you're driving it's doing useful work while getting warm.
You might look into a block or oil pan heater to warm it up on cheap grid power.
