I need to replace the cabinets, countertops, and replace the vinyl
flooring with tiles in the kitchen. Is it safe to do so when the wife
is 8 weeks pregnant?

Should be. It will not be better later with a newborn.

I won't be re-painting the kitchen, but what
about the dust and other things that might be airborne during the
remodeling? I expect it to take about 2-4 weeks, depending on how fast

If they are reputable folks, this won't be that much of a problem. Ask them
to aim at 2 weeks though due to the prenancy issue and her needing not too
much disruption.

the contractor can do it. I have most of the needed stuff in the
garage already (taking up space which is one reason I want to get it
done now) This is a single story home and the heater will be OFF
during the entire time.

This is more of an issue than dust if you live north and essential once the
baby is born so you can't do it in winter next year.

I'd just like to get this done before moving on to more pressing
matters. but if it's a really bad idea, then I don't have to do it.
Or I may have her stay with relatives during that time if it's OK to
do it only if she's not present during the entire operation...

If you have a cold snap, might be best to stay with family for a day or so.
I presume here you don't live too far north or you couldnt shut off the heat
long at all.

Any reason why you have to turn the heat off? That is pretty wierd.
