Not trying to plug Wayne's speakers to get him a sale, as much as save you some time. From your inquiry, you seem very sophisticated in general, but starting out in the SET world. If you enjoy the process, by all means have at it. Maybe you'll find something new that will be a big help to all of us. But, judging from your questions, I was guessing that you might end up somewhere where Wayne already is (mean that as a compliment.) I think Wayne has some of the best prices on Eminence products, so he doesn't really need a plug to sell them.

What type of amp does your friend have, and what power tube and iron does it have?
