The reason I said to collect food first is because when you are getting rushed/being harassed it is easier for them to take you off the hunts then the coin mine next to your base (assuming you have one)
You start building the TP soon after you hit age 2 with the 400 wood u collected.
You do get 2 shipments in colonial. The 3 SW first followed by the 700 wood if you choose the eco FF and then you have one ready when you hit age 3.
With the Fast age up you send 3 SW. Your next shipment comes in and you are pretty much just about aged already so why use it on a 2nd colonial.
If you try and build the TP in transition by chopping 250 wood you simply hurt your age up time too much. =(
