Thanks for the advice - so do you mean that I can use a weed barrier to
stop weeds from coming up? If so, how much soil should be on top of the
weed barrier?

Here's a big fat hint: soil contains weed seeds. Plus, wind and rain
deposit still more seed onto soil. Thus, applying a weed barrier and
piling soil over it would accomplish exactly nothing in terms of weed
reduction.

You will have weeds. That's normal. Once the grass seed has sprouted
and been mown three times, you can treat the new lawn with an
appropriate chemical weedkiller. Or, if the area is small enough, you
can hand weed it at any time. But don't sweat the weeds. Your primary
goal is to get the grass well established. You can make getting rid of
the weeds your followup goal once the turf is well established.
