Tossing this back on the list, as I know others will have the same
questions.
Some of these items might need epoch changes. I'll describe the
specifics:

The "all caps" hardcoded dist tag is wrong. Instead, you should use
%{?dist} to let the buildsystem (both plague and brew support this)
determine what the distribution tag is. It will fill in %{dist}
with .fc6, for example. The dist tag bits are documented here:
http://fedoraproject.org/wiki/DistTag
Hardcoding the value for the dist tag is no longer allowed, since the
buildsystem can do it for you.
So, for example:
> > gdb-6.3.0.0-1.132.FC6.src.rpm
With the proper dist tag usage, this package becomes:
gdb-6.3.0.0-1.132.fc6.src.rpm
Inside the spec, you'd see:
Release: 1.132%{?dist}
rpm thinks that fc6 > FC6, so there should be no update issues in
remedying this.

This one should be pretty straightforward. Don't use Release: 0. Start
at 1.

To fix this package, all you need to do is bump the release number to 1.
cairo-java-1.0.4-1.src.rpm
> > Invalid non-numeric characters in release

The Fedora rules are pretty straightforward about non-numeric characters
in the Release field. Unless it is a pre-release package (alpha/beta) or
a snapshot release (cvs/svn), then you cannot put non-numeric characters
into the release field.
To fix these packages, the most obvious way is to strip out all the junk
that is in the Release field after the initial number, then increment
that number.
The only exception to this rule is for the dist tag, and you have to use
%{?dist} in the release field as documented. (after the integer, with
nothing else after it).
I highly encourage that you use integers in the Release field, and not
whole numbers (e.g. use 3, not 3.206), because that is the best way to
confuse rpm (rpm thinks 3.206 is newer than 3.21). We're not going to
run out of integers anytime soon.
Also, unless you're following the snapshot rules, don't put dates in the
Release field.
The full set of rules, with examples, are here:
http://fedoraproject.org/wiki/Packaging/NamingGuidelines#PackageRelease
So, some examples:

CVS falls under the snapshot rules. To handle snapshots, first identify,
is this a pre-release, or a post-release?
> > krb5-auth-dialog-0.6.cvs20060212-3.src.rpm
I'll assume this is a pre-release, and that 0.6 has yet to be released.
In this case, this package should be fixed as:
Fixed: krb5-auth-dialog-0.6-0.7.20060212cvs.src.rpm
Fixed (with dist tag): krb5-auth-dialog-0.6-0.7.20060212cvs.fc6.src.rpm
If you need to patch a pre-release or put in a new cvs checkout, you
bump the non-zero integer in the Release field, but LEAVE THE ZERO AS
ZERO. This is important.
Unfortunately, this is a case where conforming to the guidelines will
require a one-time epoch bump in the new package, since rpm thinks that
0.6.cvs20060212-3 is newer than 0.6.
Now, when 0.6 actually releases, you release a new package like:
Fixed: krb5-auth-dialog-0.6-1.src.rpm
Fixed (with dist tag): krb5-auth-dialog-0.6-1.fc6.src.rpm
> > NetworkManager-0.7.0-0.cvs20060529.1.src.rpm
I'll assume this is a post-release snapshot. Something that has come out
after 0.7.0, but I don't know if the next release will be 0.7.1 or not.
At some point in time, there was a: NetworkManager-0.7.0-1.src.rpm
The post release package would then look like:
Fixed: NetworkManager-0.7.0-2.20060529cvs.src.rpm
Fixed (with dist tag): NetworkManager-0.7.0-2.20060529cvs.fc6.src.rpm
Now, with post release packages, you should make sure that you keep
incrementing that first integer field as you make changes. So, if you
make a newer cvs checkout, say 20060611, then you'd get:
Fixed: NetworkManager-0.7.0-3.20060611cvs.src.rpm
Fixed (with dist tag): NetworkManager-0.7.0-3.20060611cvs.fc6.src.rpm
Only when you increment the Version field, should you reset the Release
back to 1. (or fail to increment it) Example:
Fixed: NetworkManager-0.7.1-1.src.rpm
Fixed (with dist tag): NetworkManager-0.7.1-1.fc6.src.rpm

Alphas are pre-releases. Even if something has been in alpha for eons.
> > cdparanoia-alpha9.8-27.1.src.rpm
Fixed, this becomes:
Fixed: cdparanoia-9.8-0.28.alpha.src.rpm
Fixed (with dist tag): cdparanoia-9.8-0.28.alpha.fc6.src.rpm
Doesn't require an epoch bump.

Same logic and naming scheme as alpha.

Underscores are not valid delimiters for any field, unless they are in
the name. This is documented here:
http://fedoraproject.org/wiki/Packaging/NamingGuidelines#NormalPackages
> > adaptx-0.9.6-1jpp_3fc.1.src.rpm
This package also has all sorts of non-numeric addon fun. We fixed him
above, but just to reillustrate:
Fixed: adaptx-0.9.6-2.src.rpm
Fixed (with dist tag): adaptx-0.9.6-2.fc6.src.rpm
> > eclipse-changelog-2.1.0_fc-1.src.rpm
This guy looks like he just needs a proper dist tag:
Fixed (with dist tag): eclipse-changelog-2.1.0-2.fc6.src.rpm
It also needs a one-time epoch bump, since rpm thinks that 2.1.0_fc >
2.1.0.
Why are we making everyone follow these rules? So that we avoid pain,
confusion, and having to make rpm cry. (Everytime I think about RPM now,
I think about Meatwad from Aqua Teen Hunger Force)
These rules ensure clean, predictable upgrades, and the ability to look
at a package and easily determine key information about it. Is it a
pre-release? Did it come from a CVS checkout?
All of the Naming Guidelines are here:
http://fedoraproject.org/wiki/Packaging/NamingGuidelines
If you're not sure if you need to bump the epoch when you make the
change, use fedora-rpmvercmp. It's in the fedora-rpmdevtools package,
and it will let you compare a Epoch:Version-Release to another
Epoch:Version-Release, and tell you what rpm thinks is greater.
