If you're not concerned about ride quality, I would go with Eibach. The Tanabe is more toward stock ride, but is stiff regardless.
Fixing the body roll, you'll need to get a strut bar and get sway bar for underneath. That will tie the two suspensions together and act as one, preventing the chassis from rolling.
