Definitely 44100

32-bit float is better

This only matters if you need to take a file at one sample rate (like
48000) and convert it to another sample rate (like 44100).
The "real-time" converter is what's used while you play, and the
"high-quality" one is the one that's used when you save. Note that
the highest-quality sample rate converter can take a long time on
slower computers, but it's worth it for the quality.
The best idea though is to try to record at the sample rate you want
in the end, so pick 44100.

CD tracks must be stereo 16-bit PCM. On Windows, they have to be
WAV files, but on Macs they can also be AIFF.
However, if you recorded something with 24-bit precision, you may
want to save a version of your recording at 24-bit or 32-bit, if
you think you may want to process it later. Saving an Audacity
project will also preserve the 32-bit precision.
Hope that helps.
