+1 to OE.
You may want to try http://byo.com/resources/hops
. and look at flavurs and styles of beer for your hops, might help.
I dry hop 30g four days into fermentation and am yet to do a hop tea so I cannot tell you the difference or which is better.
I personally use 2 - 1 - 4, using the beer fridge because I can ferment primary and secondary at the same temp. I prefer a longer conditioning period once its bottled.
There is however nothing wrong with 2-2-2 as I have used this as well.
Always remember that I have taken more out of alcohol than alcohol has taken out of me.
