Is there any way to fix this besides sanding it all again?

Is there a way to prevent this? If I do notice some glue on a good surface, how should I take care of it? I've been
using a wet rag... does that get it all?

I use regular white or yellow wood glue.

Thanks

TiteBond II yields a nice dark salmon color when shellac is
applied over even a hint of it. I hate that.

A solution Michael Fortune uses is a product called Waxalit,
a wax used on production woodworking machine working
surfaces to reduce friction. Small amount applied with
a finger tip or Q-tip where you don't want glue squeeze
out keeps the glue from sticking to the wood. A little
alcohol on a paper towel or Q-tip takes it off and doesn't
affect later finish. He found this stuff was the solution
to hours and hours of glue removal on Windsor chairs.
