Digi Or Motu, audio interfaces for snow leopart , logic pro and macbookpro Options

[canoleguer]

hello!
im new here and would like get opinions about the audio interfaces in market

firewire 800? there are only 2. It's ok wth fw400?

64 bits front 24 or 32, its necessary?

the mics pream are important? i am thinking that it would be better have a good preams and then an audio interface with several imputs.

i want to record a large piano (in stereo), acoustic bassand drums

also to compose with samples and keys wth midi /or usb.

thanks a lot for your ideas?

pd: some one speak spanish is better for me

hi,

last question:

USB.2 or Firewire 400
i think are similar
the best, FW800

and...
do you know SF-PRO24/DSP (Focusrite)?

its very cheap (300€<>) to the options (16in/8out)

and the preamp micro (2 , i think)...are good, or...?
see you (all)

up the music!!!
