I have some UPVC window frames (Bay window), and the previous
owner has put nice roman blinds on them. I want to keep the
blinds, but the sticky pad that the strings tie too keeps coming
off. Can I *safely* drill 2 small holes and install a hook held on more
firmly with two screws ? do i need special screws, or is there an
alternative option?

yeah, use small self-tappers and it'll be fine.

Also, I have a metal front door (at least, that's what it feels
like) and frame. I want to fit a door chain - again, that needs
drilling, and I've never drilled into metal... any special
screws/considerations I should consider ?

bigger self-tappers.
