winter heating solutions

So ive just ordered the cartridge style OEM heater for my 2011 v6. Im mostly looking to improve my MPGs and how quickly I can get some heat in the cab as my commute is only about 15 minutes. Also id like to prevent the nasty build up on my oil cap. I didnt go with an inline coolant heater cause they are complicated, not as effective, messy, and another place for it to leak IMO.

The OEM heater is gonna do something but im definitly going to get a pan heater as well. Ive also got a battery maintainer to keep the battery fully charged and warm as my commute is very short and my HIDS, stereo, ect. probably dont let the battery ever fully recharge. All of this is neatly wired into one plug behind my license plate.

Recap:
OEM block heater
Oil pan heater
Battery maintainer.

Now my main question is has anyone ever put a heater on your 6 speed manual transmission? even with mobil 1 in the trans the cold shifting sucks especially with the URD short shifter.

What are your experiences with the trans heater?
Should I just get a heater similar to the oil pan heater?

 

I live in western Maine and we have had a good spell of 10 to 20 below temps and day time highs in the single numbers mine starts fine trans works fine and I have heat in about a mile or so. I do not warm it up (0 MPG) just get in and drive. No matter what you do short trips are going to kill your mileage winter weather costs me about 50 miles a tank full. Shoot I have to drive 15 mins to the ATM! Where ever you go are they going to let you plug it in when you get there?
