Need to verify initial settings for US -- please comment

Ok so for US users:

turn on wifi and change GB to US

leave GB so the scripts will work
add en_US.UTF8
do I need to add any of the other en_US.*'s ?

I am on the Pacific coast and there is Pacific Ocean and Pacific - New. (What the heck is Pacific - New ?)
I have been using Pacific Ocean.

I haven’t figured out what I can use for an US keyboard layout and the default works for now.
Suggestions on a US keyboard layout ?

I can’t find anything else I have to change as an US user, please comment if you know of something .


That is what I use, well central time
