Ted,

I used Photoshop CS2, so I'm a few versions behind on it. You can use any software that offers curves adjustments, including Lightroom, Photoshop Elements, and Paint Shop Pro. Each of them I worked on received two curves adjustments. One to set overall contrast and a second to fine tune tonality. Getting an exact match to someone else's adjustments is probably impossible, so if you got them looking good I wouldn't sweat it.

If you decide to get into darkroom printing, they'll probably print fine on standard grade 2 paper, but if you use VC paper, you can adjust contrast with it and get results that match closely to what I got in Photoshop.
