I probably don't have enough experience to give you an exhaustive list.
However, since this is a web development, the two biggest points I'd be
looking at are:
1. How do they plan to separate the production environment from testing
and development? You don't want to crash your site just because the dev
is too lazy to test his changes beforehand.
2. Do they have a basic understanding about web security? What
precautions do they take with regard to XSS, CSRF and the classic
injections (HTTP header, SQL, Shell, etc.)? Do these words even ring a
bell to them?

Methodology is also a good indicator: Are they happy hackers with no
real software engineering background, then they'll probably be good for
smaller projects but will break down on large ones where you need the
additional management. On the other hand, if they throw only buzzwords
at you, I'd get suspicious.

Two independent programmers working on the same project? I wouldn't do
that unless they know each other and have experience working together.
If you need to scale beyond the capabilities of your contractor, you
should definitely start with a larger contractor (i.e. the company).

I cannot give you any insight on agile development. First and foremost
because I've never worked agile (well, unless you count rapid
prototyping) but also because that's one of those buzzwords that can
mean many different things to different people.

Not completely but it's definitely better than managing two developers.
You should still try to be in close contact with them. See if they
understand your requirements, watch their progress, look at their
intermediate results, plan the final acceptance testing with them and so on.
