Audio I/O Interface and Other Newbie Questions

Thank you everyone for your excellent help and insight about bit depth 
vs. sampling rate and on audio I/O devices!  Considering that I'll 
probably want to do lots of "tweaking" to my audio files after 
recording them, I can definitely see the wisdom in having extra bits to 
play with. I can also see the value in wanting the option of being able 
to take advantage of potential future formats (such as DVD-audio) that 
utilize higher bit depth and sample rates.  So yes, I'll be shooting 
for a 24-bit/96 kHz interface.  Speaking of which, it seems that just 
about everyone feels the MOTU 828 is the best non-internal device out 
there that's within a relatively reasonable price range (not that I 
don't agree with Mike that the digi002 is incredibly cool, albeit 
notably higher priced).

So in other words, all my questions have been answered. Again, thank 
you all so much for generously taking the time to help me out!
