Well, I feel a little inadequate... my 500 AD post is not a complete game.

However, I am playing for a culture win so I suppose its OK.
Some of my early decisions:
Moscow:
Moved the settler to the plains hill, decided I liked the original spot and went back. Cost me a turn, but I thought the plains hill brought too many desert tiles into the fat cross for a culture city.
Huts:
jar2574, 3 settlers? I am jealous! I did pop a worker, then a settler. As I recall, my other hut pops were maps and gold, no techs at all. One issue, I lost my first scout to a lion very early on, so I didnt get too many huts (maybe 5-6 total). Bit of bad luck, in my practice games, the barb animals seemed pretty wimpy.
Key cities:
I founded St. Pete to the north of Moscow. 4 cows were whispering in my ear
GP factory, GP factory. I decided that due west of Moscow would be a good site for my second culture city (Rostov). I was sold by three gold mines and some flood plains for cottages (including one to the east of the mountains in Moscows fat cross). Also, lots of trees to chop wonders. I didnt really see a great site for culture city three
I eventually picked a site to the southwest that had several flood plains and a silver mine. The problem was it had no trees. I founded Novgorod there and cottaged up the flood plains. After exploring, I decided that Maos capital was a much nicer looking site for culture city 3. It had gold, silver, a couple of flood plains, and lots of trees. So, I
ummm
borrowed it from him.

I went back to Novgorod, farmed over all the cottages, and made it GP factory #2. Wasnt a great GP factory, but I did eventually get two artists from it. Beijing was culture city three.
Other cities:
By 500 AD, I had built a couple of other cities as well. One was sited to get the stone south of Moscow for wonder building. The other was to hook up corn. With this particular map, health bonuses were the limiting factor on speed for culture
really cramped my GP factories and culture cities.
Chopping:
For me, this was a bit of a challenge, because Im generally a chopaholic. However, with the health situation, I decided to leave 4 forest tiles in St. Pete, 2 in Moscow, and 2 in Rostov. Holding off chopping did slow down wonder creation, but I thought Id benefit from the extra population, especially in St. Pete.
Early Wonders:
Moscow: 1425 BC - Stonehenge, 940 BC - Oracle, 360 BC - Parthenon
Rostov: 300BC Pyramids
St. Pete: 230 AD - National Epic
Early Techs:
Some comments on my tech decisions. Youll notice bronze working was kind of late. My rationale was that I would be doing less chopping (health concerns). I also wanted to wait until I got the Stone hooked up so my Pyramids chopping would have higher value. Finally, I assumed I could get away without Axes for a while. So, my first techs were to get my GP farm and cottages going. Then I went for religions so I wouldnt need to depend on AIs spreading them to me. One other comment, I made several trades for pretty useless techs (e.g. Sailing). These were done for diplomatic purposes only.

100 AD: Music (free GA)
200 AD: Paper
380 AD: Edumacation
Warmongering:
Sigh.... only one war

. I decided I wanted Beijing as a culture city. Started the war in 140 BC, captured Beijing in 20 BC, razed his other two cities. Mao out in 20 BC. IIRC, even at this late date, I only used Axemen.
Civics:
I did not switch to Caste System when I discovered CoL. My GP factory was not up to speed yet, wanted to combine it with another civic to limit anarchy. I dont remember why I waited on Representation, I assume happiness was not an issue when I completed Pyramids. Or, maybe I was asleep at the wheel.
920 BC: Caste System and Bureaucracy
20 BC: Representation and Organized Religion
Religion:
I felt I had bad luck on Religions. I had gotten a Great Prophet from Stonehenge and Oracle, held him with the hope I would found a religion in a culture city and make use of the shrine for culture and gold. I ultimately founded 5 religions, 4 of these founded in my GP farm cities, so I did not want to build their shrines. The fifth was in a nothing city. After all that waiting, I used the Prophet as a super specialist.
20 AD: Adopted Hinduism. - Picked Hinduism so that Vicky would be my bud. This is about when I started spamming temples, so I wanted to be able to go to OR and get the building bonus.
Diplomacy:
Based on the global politics, I decided to be pals with Vicky and Roosevelt since they were close to me and were chummy with each other. They had issues with the other AIs, so I limited all of my early trading to these two. Adopting Hinduism made Roosevelt cautious for a while, but I gave him some free stuff and he came around.
500 AD Status:
Hanging Gardens and Notre Dame are almost done. Liberalism is only a couple of turns away. 7 cities built, working on a Settler for city 8 (planning on 9 total). St. Pete and Novgorod are building artists (3 complete, plus 1 from Music). Mao is bye-bye, Im hoping I am done all wars.
What would I have done differently?
In hindsight, I jumped into wonder production too early. I should have gotten libraries up in my culture towns first. I think my tech pace could have been much better. I'm also thinking I should have switched to OR sooner to speed up my wonders. Not sure about that though.
My city locations:
Two culture cities (Moscow and Rostov) and my main GP farm (St. Petersburg):
Beijing -3rd culture city donated to me by Mao:
Novgorod being converted into a 2nd GP factory and a couple of resource cities:
