I think you did very well! That is some killer gear and the SVT-4pro was my first professional head and I still have it to this day.
You're definitely on the right track of tapping into the potential of what this amp can do. I highly recommend that you download the manual and give it a good study. Bi-amping and running an effects processor are outlined in the manual and there's lots of good information.
Another piece of gear to keep your eye on is an SVP-1600 power amp. It's an SVT 4pro power section without the preamp. There is a vague diagram (IMO) of this amp being bi-amped with the 4 Pro to provide an additional 1600 watts into another set of cabs.
More than likely, you'll never need 3200 watts, a heavy flight case, and four 810's unless you're a professional touring musician with roadies in tow. However, it's good to know that this is a well thought out piece of kit with lots of options and features. It's not a 'plug and play' amp and you really need to pay attention to what you're doing when operating it. I believe many of the misconceptions of it being 'weak' and 'underwhelming' are due to users slamming a cab into it and expecting the finger of god results. It has a three-tube preamp section and will stay warm and clean at high volume -- even with the gain pushed. Like all Ampeg products from that era, take the limiter light with as a notification instead of a warning. Using a dirt pedal is recommended if that is what your seeking.
Congrats and best of luck to you.
