shade plants and where to get them

I am starting to get some serious enjoyment out of improving my garden after finishing interior work on my 100 year old house (took 3 years). I have a lot of shaded areas including by my driveway and the rear of the house which shades a couple of other areas. I planted hostas on the left side of my driveway and they thrived but I want to do something different on the right side. Any thoughts? This area is closer to full shade than part shade (zone 5b) For the rear which is partial shade I have heuchera in one part and columbines in another. I just planted them so I don't know how well they will do but I still have plenty of space to cover. Any suggestions as well as tips as to where to buy plants inexpensively online would be appreciated.
