Hopefully yes... :-)

Firewire is working fine for some users but you have to make sure that
the card you buy is indeed well supported under linux. In that respect
f8 is not as good as f7, I still have to sink time into that (apparently
the stock fedora kernel does better in that respect).

So far nothing beats the latency numbers you can get with good and
supported pci soundcards. I briefly tested an edirol 101 and it worked
fine for output latencies but the roundtrip latency (input + output) was
not that good. 

USB I would not buy (unless there have been changes I'm not aware of),
the restriction of packet transmissions hardwired at 1mSec makes working
with 44.1KHz sampling rate not so good with Jack and friends.

You could also try gparted, there is a cd image you can download that
boots into a partitioner similar to Partition Magic. I have used it on a
couple of occassions with success. Obviously you _really_ want to have
backups of the data on the disk... (whatever you use).

I normally use the default which is ext3 on Fedora. There have been many
threads on the linux audio lists and some users favor things like xfs
for the disk where they store soundfiles (it is faster at erasing big
files). My guess is that ext3 has seen a _lot_ of use with the
consequence of stability - which is number one in what you want from a
filesystem.
