What are the AAC Sample Rate and Bit Rate settings to set in order to encode an audio track with a quality comparable to MP3 320kbps?

I need to backup a DVD movie, the default settings for AAC are

Bitrate (KB/s) 128 
Sample Rate (HZ) 44100

should I set

Bitrate (KB/s) 320
Sample Rate (HZ) 48000

or the default are already good?
