PLA doesn't produce fumes - with ABS you need some ventilation.

For PLA a dilute solution of PVA applied to the glass bed helps it to stick and the parts come off quite easily when the bed cools.

Operating in a warm environment helps minimise warping.

If you are printing fine detail or small objects a cooling fan helps - it should be turned on after the first layer has been deposited.

Be prepared for some experimenting....
