Question #1: My rosebushes had yellow spotted leaves last Fall so I cut them all down to the ground. Now one has started to grow back and looks healthy so far. Should I leave it alone and see what happens? Is it possible for the regrowth to be healthy?
Question #2: I have bag worms in a Bradford pear tree. What can I do to kill them and prevent them from coming back?

When you said spotted, it makes me think of "black spot". Remove ALL of the old leaves, even the ones on the ground.
I often use a 5 in 1 spray that I buy from Wal-Mart, and it works great, and covers more than one rose disease.
My sister in law uses I think sulfur in a spray bottle. I could be wrong on her spray bottle, but her's is much cheaper, and I'll be using it this year. Sorry, I can't help you with the pear tree.
Why are my rose bush leaves turning yellow all of a sudden? It sounds like your roses have experienced a fungal disease called Black Spot.
