removing seed pod and also cutting back a clematis

Question

now that my butterfly weed plants have beautifully covered the planting bed I am wondering if it is alright to remove the seed pods as I do not have room for more plants popping up.
I have and older clematis that blooms in spring and occasionally a bloom or two in summer it is getting unruly if cut back down to about 18″ will it do harm?
