Sorry I can't answer very much of this, but:

1. Sage is perennial. It will flower every year once established. Its flowers are lovely and very popular with bumblebees. The flowers may come at the expense of the leaves to a small extent, but the leaves are still perfectly good to use in your cooking (or indeed raw in salads if that's to your taste). If its in good soil the flowers won't cause any problem at all on Sage.

Basil is an annual I believe. One it flowers, the leaves are not great. The flavour deteriorates but their still edible.

Parsley is biennial. If it's flowering it is almost certainly its second year and coming to the end of its life. The leaves and stems are still edible but won't taste as good, and may be a bit stringy.
