If want to see only your own tracks, press Shift+G in Potlatch, or load
the files from a local disk in Merkaartor or JOSM. That way you won't
see the "noisy" tracks.

No. GPS traces are just evidence, or a guide, and shouldn't be
interpreted literally. If they look messy, it's OK, since they're only
used for tracing. The amount of work needed to clean up the traces would
be massive (it would need to be done by hand), and we'd gain very little
-- it doesn't generally affect the accuracy of mapping.

Some people do clean up their own traces before uploading them, but that
is based on their personal knowledge of which bits of the track are
accurate, and which aren't. It's not something another mapper could do
easily.
