Be sure to check out the new Plan Builder. It is meant for this purpose exactly:
As a general comment on your questions above, I’d be hesitant to head into High Volume anything. That is unless you have a history of handling LOTS of stress, especially indoor stress (which can be more demanding to many people than outdoor stress).
Based on your limited 2 year training history, and your age, it seems High Volume would not be the best bet. But that is me being conservative. We have seen so many people bite of more than they can chew, crash and burn from too much work and/or to little recovery.
Up to you, but realize that HV plans are meant for those that really can handle a lot of stress (and have time to recover properly).
