This really is a true regenerator gauntlet. I fully agree Plains is the only viable map type; no other map has similar clusters of resources.
I don't think I have the patience to try to get that perfect start, so I'll make some observations and theorycraft.
Wonders: Pyramids is a must for Representation. Using the Oracle to grab Education for a faster Oxford is worth it. Ironworks is a must with coal/iron. The Globe Theater tends to generate too many GA and should be put off as long as possible, but should be built if you have enough food surplus and need the happy. The Epic is worth chance of GAs in most cases. The only other wonders really worth considering are Stonehenge, the Hanging Gardens, and the Great Library. With stone, Stonehenge and the Hanging Gardens are much more attractive. The GL is questionable. Without marble, it takes a while to build. It also obsoletes quickly, forcing you to delay Sci Meth to make the most of it. The Parthenon tends to make more GAs than the boost is worth and is hard to build without marble.
Tech path: Well, since this is an OCC end date comes down to what you build, what you tech, and what the computer gives you in terms of map and AI activity. Techwise, we want to trade for as much as possible and get techs that let us build spaceship parts, wonders, or enhance research or hammer output. So the first couple of important techs are going to be pottery, alphabet, and bronze working. Next comes Civil Service for Bureaucracy and Education for Oxfords.
After Education things become much less clear. Useful techs at this point are Philosophy (Pacifism), Printing Press (+1 commerce per town), Literature (Epic, GL), Astronomy (+25% beaker observatory), currency (assuming the AI haven’t traded it to you yet, +1 trade route), and music (free +3 base beakers over [at +225% that’s 9 beakers per turn for a 600 beaker tech, so music is worth it]).
After backfilling some or all of the preceding techs, you move back up the tech tree either going for Assembly Line (with the intention of getting Industrialism next and picking up Economics (merchant) and Corporation (+1 trade route) along the way) OR going directly on to Rocketry. Bypassing Assembly Line early means you miss out on the productive boosts from the factory and Al for a while, but gives the AI a chance to research some stuff for you. Since production is generally the limiting factor, not research, Rocketry => Computers generally makes more sense than the other way round.
You'll notice I haven't mentioned Liberalism yet. Liberalism is very important, of course, but the timing is interesting. Wait too long and either the AI will beat you too it or the AI will be too backward to ever learn anything for you to trade from them. On Warlord you can get Future Tech with liberalism, but delaying too long is NOT worth it. Personally I think grabbing either Computers or Industrialism is the best option; both are 6435 beaker techs and give you time to gift the AI up to speed so they can try to learn something that you want them to learn.
After that its all spaceship techs, plus railroad if you have coal and are really hammer poor. The only spaceship techs that help you tech along are Fusion, Biology, Genetics, and Robotics. You'll have to judge for yourself if the food, GE, or Space Elevator (I kinda don't think the elevator is ever going to be worth it, but it might, I guess) will help you more, while making sure you keep learning spaceship techs fast enough to be working on a part at all times.
