The problem now are shoots coming up everywhere from roots still under
the surface out within 6-12 feet of the old stumps. Will these
eventually diminish and die out? I pull them regularly.

You don't even have to pull them, unless you're running around there
barefoot. Just mow right over them and they'll stop in a couple years.

If you don't want to keep mowing, apply Roundup with a paint brush to the
shoots.
