Delete large quantities of small lines?

Auto Trace often leaves small hatchmarks. The Reduce points tool doesn't help, and often, there are several hundred of these, no matter where I set the threshold on the trace tool.



There must be something I'm missing. Perhaps a way to prevent it from happening in the first place?

Yow, that looks messy.

Here's what I'd do: Shift-click on the shapes you want to keep, cut and paste them in a new layer. Delete the old layer with all the 'hash marks' and stray points. This might be quicker since there are fewer keepers and they will be easier to select.

Alternatively, it might be easier to use the lasso to select the 'hash marks' and stray points instead of clicking on them.

As for optimizing AutoTrace, I haven't used that feature...sorry. Does it do this with any image or just this particular image?

It looks like you've used a grainy or heavily compressed picture as source. Better source = better tracing.
