Welcome back from the Dark Side.
Of course this is all personal preference. You didn't mention if you are PBEM or against the AI....
First thought, you do not really need to touch every unit on the board on the first game turn. You have the luxury of some time in areas that are not on the front lines. Highest priority is responding to the KB off Pearl and evacuating as much as you can out of the Philippines.
Oil, fortunately for the Allies, moving oil is not a priority. There are two small refineries in Australia (Sydney and Melbourne, I think). You can use two or three tankers out of Palembang in the first week to haul some crude oil to the South coast of Australia. Nice, but totally optional, if these two refineries run out of crude oil during the war, you can more than make up for it with fuel imports.
Fuel. You have two prime sources of fuel... West Coast USA and Abaddan (Iraq). It will take some time to find all your tankers and get them shifted. From West Coast USA I run fast tanker convoys (cruise speed of 13 knots) between Los Angeles & Pearl Harbor. Then I run slow tanker convoys (cruise speed 10 knots)from Pearl to distribute along the bases between Pearl and Noumea. From LA I run slow tanker convoys to Auckland, New Zealand... Then I use smaller tankers (8800 cargo tonnage) to distribute to Australian ports. From Abaddan, I use medium sized tankers to shuttle fuel to Bombay and Karachi. Then I use heavy tankers to haul off map to Cape Town, and another group of tankers to haul from Cape Town to Perth Australia. Note: If you play the AI, the Jap subs always seem to sniff out unescorted tankers.
1st turn, I send all Clemson Destroyers in Seattle/San Francisco to shipyard APD conversions. I order all Clemson DMS's and DM's from Pearl to head to the West Coast USA to provide escorts for transports/air transport/tanker convoys. They are unimpressive escorts, but just being present can drive away a Jap sub after the first attack.
There are three British troop convoys at sea at game start. Two off the West Coast of India and one just off map coming from Cape Town. I like to redirect them to Columbo port, toggled 'Do Not Unload'. That gives me the chance to assign escorts and make the final determination of where to send them.
You have some Base Forces/Headquarters and a Marine Regiment on the West Coast that can be shipped overseas without using political points. Pago Pago is the first troop convoy destination for me. I ship troops out of San Francisco and Fuel/Air Transport/Supply Convoys out of Los Angeles.
Then over the first four-five game turns, I hunt through the ship listings tool finding classes of freighters to get moving. It will take a month or so to get them all sorted to their base ports and get the shipping convoys set up.
Lastly, (easy to over look), check the scheduled ship withdraw list. Queen Elizabeth in Sydney and one of the transports in Singapore need to start heading off map. You don't want them working a transport mission, only to discover you could lose PP's early in the game.
The rest really begins to be up to you. Just a few thoughts..... enjoy the early days.... I find once you get things moving in the first week of game turns, you can quickly turn around your game planning (as you wait for those reinforcements to arrive).
