NewB Sample rate Qn

[YNM]

I was reading the spec pages on SB2 and came across something that confused me. Regarding the Digital S/PDIF outputs the spec says "Sample rates: 44.1Khz, 48Khz ". More complete text for digital outputs reproduced at end from:
http://www.slimdevices.com/pi_specs.html

My question is: are the sample rates mentioned in there different from the MP3 and other bit-rates...192K MP3, for instance ?????

If the SB2 ends up processing FLAC or other lossless stream, will I get "lossless" digital stream on the digital out? I plan to stream that into a Rotel pre-amp for 2-channel listening. If there is information loss, I might as well use an iPOD dock and save a bit of hassle.

Thanks, in advance, for your responses.


Digital S/PDIF outputs
======================
Optical and coax digital connections
Dedicated high-precision crystal oscillators (no PLL, no resampling)
Standard IEC-958 (S/PDIF) encoding
Optical connector: TOSLINK 660nm
Coax connector: RCA, 500mVpp into 75 ohms
Sample rates: 44.1Khz, 48Khz
Audio format: linear PCM, 16 or 24 bits per sample

The mp3 "rates" are delivery file stream rates.

The SqueezeBox rates refer to raw audio sample rates.
All normal CDs are 44.1 k samples per second. Since these
are defined as two channel 16 bits per sample, you take
44100*2*16 and get 1,411,200 bits per second.

Roughtly 8 times the data of your example 192K MP3

yes. perfectly lossless.
