Help! Rambling rose, wisteria, and butterfly bush mess!

[Jadeco]

Hello, I just moved into a new residence and started tending to the backyard garden this summer. There is a rambling rose that hasn't been pruned for about 8 years (I know because my parents lived here during that time.) I started by pruning back the dead &/or diseased branches and cutting back the canes on the rambling rose bush.

The wisteria is also tangled up in the rose plant on one side, and I have never seen it bloom. I'm not particularly interested in forcing it to bloom, but want to know if I should move the wisteria plant.

Also, there is a very tall butterfly bush in the midst of this mess. It's so tall that the blooms are laying on the neighbor's roof! Should I move that, too?

Thanks.
