It depends on whether the said subcomponents are part of only that
component. If not (that is same subcomponent is part of multiple
components), it may be easier to look at it as a component itself and let
them be in parallel directories.

Not quiet sure I understand this correctly, but may be you could have a
structure like:
/components
- comp1/1.0.0
/1.0.2
/2.0.0-DEV
- comp2/3.1.0
/3.1.2
etc? And as you suggest later you could use judicious use of externals to
check these out. The external could refer to comp1 as
$MY_SVN_ROOT/components/comp1/1.0.2 comps/comp1
In this case the SVN structure has the version number but the checked out
source does not. You can still get the revision being used by querying the
externals (depending on the need, you will have to write a small script to
get all the externals / version info)
I think my problem is close to how mingw looks:

This is tricky. If you want to do changes and do an atomic commit to
components checked out as externals and source code that is not checked out
as externals, I don't think it is possible. I may be wrong.
We have had situations like this, but in such situations, we checked out the
source code separately and did the changes (That is even though a component
is checked out as external, since it is in the same repository, we can check
it out as a separate folder -- the while components/ directory in the above
structure for example). It may be a little bit of a overhead though.
4) Is there any kind of support for questions like: "Is there a newer

I guess you will have to write some scripts to query externals to do this.
Hope this helps
