Those values seem fine; particular values are pretty arbitrary, you just have to change multiple units in sync, to retain balance. But even if those values are perfect, I still see a problem, which is that Lancers at Metallurgy are only a single tech ahead of cavalry. It's just a function of working within this condensed tech tree, where each era is only 'two techs long.' By the time you actually build a lancer or two, you can have the tech for cavs. The 'pedia description has them dominating the Renaissance... but by the time you build some the Renaissance is over! I'd like to move them earlier, but Lancers at Printing Press... makes no sense. You could move them to gunpowder, but then you could build Lancers without ever teching Horseback Riding! Sigh. Every change affects many other things, there's no perfect solution.
That's why I thought to move (slightly weakened) Knights back to Civil Service, and move (slightly differentiated) Lancers back to Chivalry. Chivalry has two other prerequisite techs, so it's unlikely you'll go straight there from Civil Service; and even if you do, giving the Lancer different characteristics and resource requirements means that Knights won't necessarily be obsolete. Moving this Renaissance unit to the medieval era is a bit of a big deal, but it's at the end of the medieval era, and it lets you use them all through the Renaissance. But to each his own - I'm not arguing for one thing or another, just brainstorming.
