Anyway to improve ultra-cold start ups?

Hey everyone, I just wanted to start a technical oriented thread here for those of us who have already done extensive maintenance. If you just bought your E46 and did not even replace anything yet, then you need to get out...your car probably runs rough in the morning due to zero maintenance.

So- I went outside this morning at a cripsy 8 degrees and turned the key to Position 2 several times to wake the electronics and prime the fuel system (not to mention electronics were super laggy). Then fired up. Dash lit up like a christmas tree as the car cranked once and then ignited, making noises of all kind. All the lights went out, no check engine lights either...but the engine was making retarded forms of foreign noises. Being a great fanatic that I am, I knew my car had been sitting for 3 days straight, and even in summer weather, if the car sits for a while it runs rough for a few minutes. So I took her on a 5 mile drive and let the temp gauge get to middle and then cruised around town, engine made no more noises. Then I came back and pulled into the garage (since my mom left) and that is where she currently sits, with no problems.

So my question is- is there some form of maintenance that I still need to do to help this situation out? Or is the fact that my car has basically been an ice cube outside for 3 days? It probably has to deal with the ultra-cold oil on the start up that caused all the raucous.

I already did Spark Plugs, Entire Cooling System, Pulleys, Belts, Fuel Pump, intake boots, ICV clean, entire CCV system cold weather edition, entire vacuum system, new gas cap, fuel additives every 3,000 miles, only been using BMW 5W-30 oil, and much much more.

What could I possibly do? I was thinking about getting BG MOA and adding it to my oil, which should greatly improve startups. Or should I not let my car sit for 3 days straight?
I'm tired of waking up in the morning looking like in fear of my car start up. I wanna look like
