The new growth on last year's dusty Miller appears to have budding flowers on the very top, does dusty Miller flower?
Yes, Dusty Miller will flower, though many gardeners pinch off the flowers to promote more fully leafing plants.
My dusty miller leaves look wilted and the stalk is brown does that mean it is dead or should I try to trim it back and if so how do I do that? I think I may have overwatered it.
Make sure the soil is well draining. If the soil is soggy it can cause the death of the plant.
Dusty Miller plants in pots have doing well and the all of a sudden some look black at the root and limp.?
Is the soil wet? Soggy soil or poorly draining soil could lead to root rot or fungus issues.

In areas colder than zone 8 it will will be an annual and can be discarded after it dies. In areas warmer than this, it can be trimmed back now or in spring.

This, really, depends on your area, climate, and many other factors. This article will give you a good idea, if given the correct environment: https://www.gardeningknowhow.com/ornamental/foliage/dusty-miller/growing-dusty-miller.htm
Dusty Miller is called a half-hardy perennial. It behaves as perennial in zones 7 or warmer but may suffer winter kill north of that. Like snapdragons, they sometimes come back in the north particularly if winter is mild or snowfall covers them, giving protection from cold winter winds. The dead foliage is part of what is protecting your plants. If you trim it back, you need to substitute a 1-2 inch layer of mulch over the plant crowns.
Can you pinch tops of dusty Miller for fullness? When is it best to do? .
You can pinch them back midsummer to keep them from growing too tall.
