I presume you're referring to Thunbergia, the Black Eyed Susan vine - lovely plant - we had a big pot full growing up a wigwam on our front porch - looked fantastic. Yes, it's a half hardy annual, so remove it now.
As for the clematis, not really anything that needs doing at this time of year - a mulch of organic matter around the base would be good. Then in the spring check which pruning group your variety is in and prune accordingly.
