I like to move things around in fall if possible, so their roots have a chance to get re-established and also because there is just so much to be done in spring. I cut the flowers back to about 3", chunk them out, and mark them with a stick until they re-emerge in the spring. I also make a note in My List here at NGA where I relocated the plants so the stick is just a temporary marker (I'm not a fan of permanent plant markers in the garden, they remind me of graveyards). You may want to leave the echinacea until spring to move so the birds can enjoy the seedpods over winter. Good luck on the gallardia, mine rarely over-winter and I tend to treat them as expensive annuals (still trying to find a cultivar that will be reliably hardy for me).
