The runout measuered on the body of the blade is 0.003". I think this
is too much but it could be the 'silver' coating on the Avanti blade I
just bought.

Your measurements are only as accurate as the instrument you used to do the
measuring.

Is 0.001" alignment close enough?

If you mean the blade aligned to the miter slot, that real good. + .005 and
it's generally considered that you have problems that need to be addressed

Are you sure that indeed measured "blade runout"/warp/flatness, and your
measurement does not arbor or flange runout also?

There is a specific procedure for checking the flatness of a blade with that
type of instrument:

With the instrument, find and mark the high spot on the blade; loosen the
nut and turn the blade 1/2 turn on the arbor; re-tighten the nut check for
the high spot again; if the high spot coincides with the marked spot, then
the it's due to blade warp, if not, then it's arbor or flange runout.

Arbor and flange runout on a good table saw should be less than .001"

I'm sure you'll get a lot more responses ...
