Golden Scepter makes a very nice edger. The rest of the hostas are all good choices, although you may discover that Neptune and Satisfaction will outgrow their spaces in a few years.

You might check the planting level, a few of those look to be too low in the ground. You don't want the crown planted deeply, that's one cause of crown rot.

It will look so lovely a month down the road! I agree with dhaven...the ground will settle with successive waterings/rain and the newly planted plants will settle lower. I used to lay a good-sized piece of plywood over fresh bed and walk on it to compact the soil more...then add more soil as I worked along.

Wow!! In about 15 days!
