Lynn,
current versions of osm2pgsql can import .pbf, so you are on the right
track there. Richards text is good, but it was written when planet files
were a third of the current size and is just a bit dated. If osm2pgsql
can't hold the nodes in it's cache it will have to retrieve them from
the database and that is in my and other peoples experience at least an
order of magnitude slower.
To give you current numbers, I just did (10 days ago) an import on a i7
2600, 16GB box that took 30 hours with the initial import phase running at
Processing: Node(1322468k 340.2k/s) Way(120291k 35.64k/s)
Relation(1243830 58.30/s) parse time: 28598s
Node stats: total(1322468982), max(1576326287) in 3887s
Way stats: total(120291564), max(144049709) in 3375s
Relation stats: total(1243833), max(1951174) in 21335s
Because the box has limited memory I did an earlier attempt with -C 8000
because I knew that it would swap a lot with -C 12000. However that ran
at roughly 4k/s ways and after a couple of hours I aborted it. The good
news is that you -can- import on a machine with less memory (good luck
keeping up with the updates on a VM though), for example lonvia has
imported on a machine with 6GB total (but with -C 12000).
The error message you got is weird and may point to an issue with the
export process, but it just states that the node cache is going to be
less efficient space wise, so IMHO you can simply ignore that.
So add some swap and try again :-)

I'm a rank amateur at this, can you provide a link on how to use (or
what to use instead of) osm2pgsql to import from a pbf instead of
planet-120111.osm.bz2? .pbfs are not mentioned at
http://weait.com/content/build-your-own-openstreetmap-server which is
the best reference I've found on getting a tile server running for the
planet.

Further tip: use the .pbf Files. It won't help a lot with your
current issue, but is quite a bit faster.
