Default Best apps and rom for in car install

I've now ordered all I need for mounting my Nexus 7 in my car.
There is a lot of threads about it already, but I want some good advice about rom and kernel and witch apps to install on it.

So the plan is Timur's kernel that will let me turn it on and in deep sleep with power.

Is there any other suggestions to witch kernel?

How about apps, what do I need for making my in car experience best?
