disclaimer : I did not play patched warlords, and i never used blake's mod, so I may be wrong in many things
My idea on fast workers :
1) if you pair them, you can build a road in one turn on any terrain = road opening for settlers/army.
2) they are your best scouts. Typical example : you move one worker into the next tile of your early settler. He sees if there is a threat or not. If there is, he moves back, regardless of terrain!
3) they are much faster for chopping/jungle clearing (no turn of work lost). Meaning that pyramids may be doable? highly dependant on available forest, but I'd try it if the map allows it. + mathematics is required for CS and masonry will be popped by a prophet if you don't research it (if i read well

)
My thoughts about build/researching order :
1) it depends on the map! If you have forest all around, going for BW is a must. And I'm with VoU about warrior first, then worker (in fact i'm one of those guys who argued about this strat a while ago) . If you have a few oasises, religion first and buddhism is cheaper (if you have 2 oasises, you may grab buddhism and hinduism, but i'm not fond of the hydra strat : it costs too many great people IMHO). If you have none of those 2 situations, it comes down to commerce available or not for the religion strat. If you have gold and wait a religion, work the gold hill while building a worker... (no growth lost, and commerce comes in)
2) CoL is a big thing for organized and for spiritual, it's really high priority IMHO. A good enough goal for the Oracle
3) Even though caste system allows you to run scientists without libraries, a library still gives 25% research boost. So it's better to whip away some unhappies for a library than to stop growth by running "early specialists"
4) great wall is really strong. Barbs were hard to deal with at vanilla monarch, they are much harder to deal with at warlords monarch, and i don't recall any nerfing of barbs in the patch. The GE GPP are not the only advantage!
My idea on this game :
go for it! Your honor won't be lost if the game is lost. So stick with monarch.

going for an early patched public game.
edit : you're not playing gandhi, so i was a little overboard
