Let me re-phrase... If you are using "ip ospf network point-to-multipoint"
as your network type, then the answer would be no. If you are having these
show up by virtue of it being a multipoint network that you haven't yet done
anything to, then the answer may be different...
(Shoulda read more first!) :)

Yes, there are other ways, but you have to think about what OSPF is doing
and how to fix it. :)
An area range is one method of doing that, but the difficulty is that this
command has no effect within an area, only in other areas and has to be done
on an ABR. So doing an area 0 range isn't going to accomplish a whole lot
within area 0. Good thinking though, but that's not it!
Take a look at 'show ip ospf interfaces' and see if you get a budge in the
right direction.
As for RIPv1, think like the router does. What other show commands will
tell you things?

Any way to get rid of backbone ip ospf network point-to-multipoint /32
routes?
I think the answer is no, but wanted to double check.
I tried an area 0 range command on the afflicted routers with no luck.

I also have an unrelated question.
Why does version 1 rip round a /32 192.168.x.x loopback to a /24? I have no
summary turned on. I understand this is a native class C route, but it
doesn't summarize the class B network I'm also using. To me, no auto
summary should mean no auto summary. Configs below.

<----- Why? This was a /32 on the other router.
If it's going to auto summary anyway, why not a 172.30.0.0/16 route too?
Thanks in Advance,
Michael
P.S. Also noticed that if you import /32 192.168.x.x routes, they become
/24 routes in rip.
