After seeing feedback I'm thinking:
America: UB is the Frontier Post, a Grocer replacement with 1 free merchant.
Germany: UU is now the Riesengarde, a Grenadier replacement with 15 strength.
Russia: UB is the Research Institute, now a university replacement with 1 free scientist.
And we still have the previously-mentioned changes:
Egypt: War Chariot is a chariot replacement with 2 first strikes. (25% base strength bonus on a chariot is just too good.)
Mali: Skirmisher is a 30h 4 strength archer replacement with zero first strikes. (Archer has 1, old Skirmisher had 1-2. 33% base strength increase is still really strong.)
Sumeria: Starting techs changed from Agriculture/Wheel to Agriculture/Mysticism. (Sumeria is simply one of the best civs due to combination of nice starting techs and very strong UB.)
Vikings: Trading Post gives Flanking 1 instead of Navigation 1. (Vikings are a bit overpowered on maps with water. I want all civs to have a fair shot at naval power and the extra moves are too big an advantage.)
Zulu: Impi is a spear replacement with 50% withdraw chance. (2-move spear is just too hard to balance when combined with a good UB and decent, almost unique starting techs.)
(Only change from last posting is swapping in Flanking instead of Drill for the Vikings.)
Still would like more opinions on CHA and the tech cost change I just proposed.
