Not necessarily. Cassette tape is not exactly high end material. I
don't think, your recordings will suffer much by recording them with
the onboard card. But I don't know that special board and chip
combination, so I would recommend you just try it out.
If you're not afraid of a command line application, I highly recommend
ecasound for recordings. With the cute "ecasignalview" you can check
the recording levels, tune them with alsamixer, then just use:
$ ecasound -i alsa,hw:0 -o recording.wav
to record from the first card.

The 66 probably indeed is overkill for your task. I'd second the
suggestion of a cheaper stereo card based on the ICE1712 chipset, as
the Audiophile or some Terratec or Hoontech cards. There are a lot of

I'd only recommend USB for a Laptop. PCI is much easier to set up and
works more reliable. You also get "more bang for the buck" with PCI
cards, as USB cards tend to be a little bit overpriced. But if you're
on a budget and need one card for both laptop and stationary machine
(or if you hate screwdrivers), then USB is fine as well. It provides
enough bandwidth for high quality stereo recordings.

Isolation is only necessary if you run into a ground loop: a buzzing
sound when both tape and PC are connected to the power line. You
should be able to directly connect the tape to your soundcard,
provided is has line-level inputs (most cards do). Personally I just
connected my computer to the monitoring Tape2 input/output of my hifi
amplifier, so I can also record from a vinyl record player if I want
to. (You cannot directly connect a record player to most soundcards
because of RIAA distortion, you need a real phono input.)
