I think it would be almost impossible to advise on the planting in your garden (my opinion). The shape of the bed, your preference for color blends, the location of shady spots, drier and wetter areas of the garden, etc.
For instance I just like the looks of certain foliage better than others. Are you planning on using some of these as a border, are you planning on using some to be a focal point of the planting, just on and on the issues go. So my suggestion is to get the plants and plant them in almost any order see how they do in your garden and then select where you want them. Maybe a few will multiply very fast, and you will not want them there, maybe others will just not grow in your area, just so many things that could affect your selection of plantings.
I grow my daylilies in a hodge podge manner, some all lined up like a daylily vender would have them with labels predominantly displayed, most people would not like my method, but it is my garden and I grow them the way I like. I think you will end up doing the same, planting some by the door when you walk out, a few in a bed, maybe some in a small or even large border over time. Anyhow you plant them, just enjoy growing them and the beauty and enjoyment they bring.
