Is it important to have so many, or is it reasonable to turn the modem
ones off and let the router handle these things?

It's certainly unnecessary (and maybe undesirable) for you to have two
DHCP servers; two firewalls doesn't sound like too bad a plan, in
principle at least.
But are you sure that your modem is what's doing it? Modems that I've
come across are just that, modems, with no other functions in.
Could you post makes, models etc for your various bits of kit?
So, I'm less than 100% sure whether the DHCP server which is enabled
by default on the modem, is necessary for modem purposes, or is just
an obsolete artifact of the Vigor 130's modem/router version.

I've had a quick look at the manuals and, as you say, they're really >confusing. One that I saw suggests that you can turn off the DHCP
server in the "modem"; have you tried that and if so what happens?
I've tried it turned off and turned on and it makes no immediate
difference to internet access quality or speed. I don't know if
there'll be other, longer term effects.

Well if internet speed is OK and your two DHCP servers aren't getting in
one another's way then I don't see that you've much to worry about right
now. I'd turn one of the DHCP servers off if I were you; if you're
bothered that the modem one is needed for something that's in there then
turn off the router one; but you say that it works OK with the modem one >turned off and that's what I'd do, personally, because it's untidy, and >untidiness in systems administration is never a good idea.

If I were you I'd think -- and plan -- extremely carefully before doing
that. For example, have a look at this:
https://superevr.com/blog/2013/dont-use-linksys-routers/
It doesn't matter if you don't have a Linksys router of this kind; the
point I'm making is that for security you're depending on code that
someone else has written, and for consumer-grade kit the manufacturers
don't always have the funds to harden their router code properly.
