Designer exits into the 6 version. I don't know about 7. 8 definately includes designer and admin bundled in for no charge.
Making a mistake can be costly so I'd HIGHLY recommend you talk to whomever you're buying your software from and make darn sure you have it right. IBM doesn't have a 'corporate' license but they do have some where you license the server and get clients 'free'.
Better to get a good answer from people who know than to make a mistake and pay for it during an audit.
