Fine, you should indeed have downloaded the jdk-6-doc.zip file and put
it (with the correct name) in portage's DISTDIR (DISTDIR is, by
default, /usr/portage/distfiles).

No no no, this is *not* a third party ebuild. It is an official Gentoo
ebuild, that unfortunately needs you to manually fetch this
jdk-6-doc.zip file. This is *not* a third party ebuild.
Rest assured that manually fetching files is, fortunately, very uncommon.

No. Undo this. /usr/porage/distfiles is *not* a portage overlay and
*must not* be in PORTDIR_OVERLAY. Remove it.
/usr/local/portage is a common location for putting a gentoo overlay,
but since you probably don't have an overlay (many, if not most,
people don't need an overlay), don't care about /usr/local/portage.
Remove the directory name from PORTDIR_OVERLAY and them remove the
directory /usr/local/portage itself with the command rmdir --verbose
/usr/local/portage.

Don't add features without a basic knowledge of what they mean.
In fact, this is a big lesson:
*Don't mess with your system without a basic knowledge of what you are doing*
I did it more than once and broke my system more than once. Do not
repeat the same mistake.
Look /etc/make.conf.example for a brief explanation of what which
feature means. I personally use parallell-fetch. It speeds up emerging
multiple packages, because it enables Portage to download one package
source in the background while it emerges another package in the
foreground. In fact, I don't know why this isn't enabled by default.
I don't use ccache, because AFAIK it speeds up compilation at the
expense of consuming tons of disk space. I am satisfied with my
compile speed (I use lightweight programs, and these tend to compile
quickly), but I want my disk to have a lot of free space so that disk
access is faster.
collision-protect seems nice, but I don't know about its drawbacks (if
any), and since it seems not to be default and I don't have good
knowledge of it, I didn't change the default.

No, it told you to put the file in /usr/portage/distfiles.

You don't need to, and very probably should not.
> Am I even in the right ballpark here?
No. *All* you had to do was fetch the required file and put it, with
the specified name, in Portage's DISTDIR, which is
/usr/portage/distfiles by default.
Everything else you did without knowing what you were doing should
probably be undone, to return the system to its safe default
configuration.
