...If you can keep 'em green, they should pull thru.

Agreed with the organic thing. Nice if you can get it cheap, but don't waste money when something 'generic' will do. And peat'n'perlite don't git much cheaper.

For little ones, one or two CFLs will do. 6400/6500k is good, but IMHO 4100k totally rocks for seedlings and little ones. Once they're a bit bigger, add some 6400/6500k colour, and see how they leap. And when they're very little, too much light can hurt 'em. They'll let you know when they want you to turn up the light a bit, or start (slowly!) introducing 'em to the sun outside...

Hope they recover!
